Howard Johnson's Magnetism

Max and Min RPM's

What might be called "a slight squall" came across our state today, but when it got to our location, it seemingly vanished. The rain vanished, but the winds kicked up a few notches.

The winds were "variable" to a great degree. "Turbulent" seems a bit more apt. In this environment the two whirligigs did not spin out of control. In fact, the more turbulence, the less raw spinning occurs. The larger of the two gigs reached a maximum of 60 RPM, only briefly. And while the smaller can spin faster, the variable speed of the wind caused the max RPM for only a few seconds at a time.

The average RPM is closer to 30 RPM, and so, I will calculate the number of turns of wire that will be needed in the stationary coil section of my generators, based much more closely on 30 rather than 60 revolutions per minute (RPM).

One of my next few tasks includes mapping the magnetic field of the hollow, hefty magnets. I suspect that these will exhibit more of a Howard Johnson type of bifurcation of poles than the smaller, cylindrical magnets. I suspect also, that the Howard Johnson type of bifurcation of poles may have been unintentionally derived from too many cross-sectional views, lol....

Later Note (7-24-14 noon): My earlier estimates of average RPM's of my whirligigs were clearly wrong. Average RPM is closer to 10 for the larger gig, perhaps even lower if you take the whole 24 hours of every day into the average. I have been taking counts lately because it has been windy. Now, September is supposedly the least windy month of the year for Ohio, but the greatest number of Atlantic and Gulf of Mexico Hurricanes is in September. This does not quite make sense to me, though, since hurricanes generally spill over onto land, at least making rain and wind speeds greater here eventually.

Later Still (7-24-14 5 p.m.): I caught the larger gig spinning at 60 RPM, tops, briefly. Earlier I also caught it at around 7 RPM. Calculations for how many turns for each coil will involve figuring out what percentage of each magnet's flux will cut the turns of wire; how many magnets are turning; how many coils will be living on the stator; how closely the coils will be packed; the minimum voltage required to produce a charge for a 12-volt battery, and how the stator will be wired to produce efficiency, stability, and safety at high and low wind speeds.

30 RPM's seems like a healthy clip, with 16 magnets, but I wish I already had the rotor mounted. The rotor will necessarily slow the spin down.

I am looking for a way to weigh all the rotor's parts since I have misplaced our ounce scale. A lot of housecleaning is in order, just to get all our tools organized! We have too many long term projects going on around here! Don't get me started enumerating THAT list, lol....

Harried Day

In addition to the poison ivy and weeds I am trying to eradicate, I discovered after web surfing to find a way to kill chiggers, that what people think are chigger bites are actually spider mites. They say that spider mites are quick moving and thrive in the dry weather we've been having. Lots of great information came up from the web on this topic. Soap and water get rid of the adult spider mites, but neem oil is needed to kill the eggs and larvae, so I will continue to be busy with yard and housework for the foreseeable future.

Actually, I am working toward erecting a metal building but I must first hack my way through some brush that has grown around the site and over the metal, which is how I got started on my poison ivy discovery.

Still I think about magnetic experiments throughout the days, and purchased some small wheels for new experiments today -- one metal and one plastic wheel. I will have to cut the rubber tires off them, but this year's yard work takes precedence. I had fun today touring the hardware store with new eyes, looking for parts. It felt almost as though I was touring a museum as I investigated various shapes of different metals for potential experiment parts.

My thought currently about Mylow's most recent HJ-inspired magnetic creation is that I might get the same effect with a sufficiently thick, curved ferroalloy acting as Mylow's base magnet with the three neodymium magnets perched on top, but still with the stator-rotor relationship back the way Mylow had them originally, though I can see why he changed it -- because the rotor would be too lopsided now, weight-wise.

I have other recent HJ magnetic motor experiments from YouTube floating around in my mind, so I am also trying to imagine recreating those when I tour the hardware store. I must keep my purchases to a minimum, however, so it is just as well that I only bought a few things today and that I have much yard work to accomplish before I get back to HJ magnetic motor experiments.

Dear Diary (Plus Glitch)

I must get cracking on two projects. 1a) Clear away weeds in the backyard, 1b) Look into moving the metal building floor back to its old foundation now that the trees above it have been removed; 2 a) Get cracking on building electricity generators for my whirligigs, and 2 b) Tear myself away from HJ magnetic motor experiments.

I am finding it very difficult not to think about Mylow's latest set-up on YouTube (YT). I made one practically like that and start to wonder how to negate that initial resistance. Maybe setting some smaller, larger, or multiple magnets somewhere around that initial stator magnet could absorb all the excess opposite pole's flux that appears at that point.... I cannot seem to be able to tear myself away from wondering, although at times I have actually gone back to planning and at least wondering how to accomplish specific phases of the wind powered generator project, such as figuring out how to cast an upright drum of resin that will encase the stator windings.

Also I am working on ideas for getting my workbench cleared off of the previous owner's jig so that I can make a large enough secure pad for my drill press, plus another pad for the Dremel tool. Oh I have so many projects having to do with organization that I have little time for hiking 15 miles per week to lose weight. Woe is me.

Later Note: Minor glitch: Where I was not running the riding mower over tree roots that were growing upwards, weeds grew up. Also in the enclosure that protected our cherry trees from deer nibbling, a very nasty weed has thrived: poison ivy.

I knew we had some on the upper road perimeter of our property, but poison ivy is quite insidious with its roots spreading possibly as pervasively as both honeysuckle and black walnut. It sure does get around.

Somewhat luckily -- since we also have box elder with its attendant babies growing all around our place -- poison ivy is now fruitful with its nearly grape-like bunches of white flowers and berries so that it is easy to discriminate among all the box elder leaves, which ones to avoid, but nearly every tree trunk now has poison ivy started at its base. I wonder if this poisonous sucker/parasite  runs underground along tree roots?

Giving Up on Perpetual Motion

I have just about had it with trying to make a Howard Johnson magnetic motor. Not being a physicist is probably why it took me so long to come to the conclusion that this is impossible. Magnetic fields can and do change, as does the center of gravity of a disk as you continue to pack it with various items around its circumference, but I have started thinking of magnetic fields as sort of like water. It may change for a short period of time, but it always finds its equilibrium and stays there until something else changes.
And I have come to decide that you always have to put more into a system than you can get out of it in the long run. I know. This seems counterintuitive when you think of biological systems such as human population growth. You must continually work to stop it in order to get population growth under control. Life finds a way, is what they say, but so does water flowing downhill, and magnetic fields finding their equilibrium. Magnetic fields are always balanced, even though their instantaneous adjustments make it seem that there is some way to fool Mother Nature.
And I still wonder why nuclear physicists seem to be able to make abundant energy when matter and energy are neither created nor destroyed. Tell that to Hiroshima!
But anyway, as with cigarettes, I hope to finally mature enough to put away childish things, and get back to productive enterprises. At least I finally feel that it is a dream, rather than simply accepting authority because everyone else does so....
And I can still use the magnets to make electricity generators, btw.

No Joy

I attempted to build krudelta's model of HJ's magnetic motor today, although I did not have a small enough metallic wheel, nor the hole-filled metal blocks. I tried to make do with what I have but achieved "no joy in Mudville." Tomorrow I will tinker some more, gerry-rigging here and there to try to approximate what krudelta had in the way of metallic infrastructure, even though I can not be certain that his wheel rim was metallic.

Having ferromagnetic infrastructure definitely alters the magnetic fields that play together, but just because something is shiny does not guarantee it is metal.... Too many potential variables exist on that video. No explanation for how or why the magnets are arranged the way krudelta has them reminds me of the video made by a member of the "National Sarcasm Society." Oh, I got a bit of movement, finally, of the wheel, without bouncing back, which is encouraging, so I will tinker some more tomorrow....

Mylow Project

While surfing the YT fare for Howard Johnson magnetic motor videos I ran into Mylow's channel at Mylow's Channel. His older videos are not there. I wonder why?

Anyway, his newer video shows sort of half the circumference of a drum set-up packed with lined up bar magnets, while the rotor horseshoe magnet has three neodymium magnets on its back. It turns all the way around, then bounces off the starting point.

He should try this set-up with three or four rotor magnets so that there will always be two rotor magnets pushing when a single rotor magnet hits that start point. He has already proved that a bit of excess force will get the rotor magnet beyond the start point...

I write this here because no comments are allowed at his channel site. How can I talk to him?

I just subscribed to his channel. Maybe he will send me a message so I can get his email address?

"Free Energy Magnet Motor"

In between yard and housework duties, and thumb twiddling such as TV watching and playing computer solitaire, I sometimes watch YT videos of the magnetic motor topic. Today I saw two that keep me pretty interested. The latest was posted by "The shiz" with no explanation and often too dark video to make out anything, but "what the hey?" Anyway, its link is "Free Energy Magnet Motor by The shiz." At 0:26-30 seconds on the video you get what seems to be the clearest views of the rotor magnets. It looks ingenious the way the gaps are staggered among the multiple tiers.

What material the drum is made from -- and the base for that matter since it is so dark -- are two questions I have. Why The shiz has no explanation and makes no claims beyond the title of the video -- which I made the title of this entry -- are two more questions.

Where The shiz got the magnets is another question since they must be somewhat round to stay on the drum surface, but appear to taper. With the shadow or lines at the right end of each of the stator magnets I wonder if they are thicker on one end, too, but maybe what looks like shadows are only a marks for where to place the magnets.

[Later Note: Another video has this same offset pattern with the thicker end on one side but it is made from screws at "Free Energy Magnet Motor" YouTube (YT). Another one of these is built by another person and it is labeled "debunked" at YT, but the fellow does not bring his stator magnets as close to the screws as the first, and he spins it in the opposite direction, which is also different from the principle of the first.]

The first video that looked interesting to me today I found using the "10000 challenge magnet motor" Google search string. It resides at IAN5577 and I do not understand the comments. How do those comments get onto the video? Was it ian5577 who put those comments there? Has ian5577 ever tried to build one of these experimental rigs, or is he simply a nay-sayer from the get-go?

Later Note: Here is a dandy video! "Standing Start to 6000 RPM's." I think this one is the best yet! It has the least number of magnets! I hope it is not a fake! krudelta is the handle of this video maker. Like The shiz this video maker seems to make art flicks and has no other videos about magnetic motors.

[Later Comments: The Standing Start to 6000 rpm's video leaves me wondering why krudelta would make it if it is a fake -- which is entirely possible -- other than he has over 100,000 hits on this but far fewer hits on his other videos.

Why the blocks he uses to keep the main plane off the table have all those holes in them makes me suspicious. Certainly video trickery is very possible here because an electromagnet could easily have been strung between those holes in the blocks underneath the main plane, while, since he has made other videos, his video editing abilities could easily have eliminated a portion of his tear-down procedure. Why has he not shown the underside of the main plane while the wheel is in motion? Although, video of that could also be edited together so that no electromagnetic motor underneath would appear.]

I see there are several other high RPM magnet motors posted at YT (You Tube) so I will be looking for them, too. [Later note: But instead, I found the "Perpetual Motion Machines (hypothetical)" YT video.]

Thoughts on HJ Magnet Dimensions

The blog at K & J Magnetics has an article on redirecting magnetic flux using metal. As I am experimenting with this concept regarding the peculiar shape that Howard Johnson advocates for his rotor magnets (which I use as stator magnets, instead), I suddenly realized today that I do not have to make the poles nearly knife-edged. If I were to do that then flux would escape because a certain minimum thickness is required of the metal being used for redirecting the flux.

It also occurs to me that perhaps what I think would be a DC generator would not, in fact, be DC until I rectify the current produced. I was going to face one pole toward the wires, from all my magnets in order to avoid the constant "slamming" back and forth of the current. However, it might be possible that in between the magnets the magnetic flux direction would alternate. At least there is a 190 degree shift between the center of the facing pole and the edges of the field as it returns to the opposite pole.

I have yet to actually build my generator in order to take readings off its current, but sometime this summer I should be able to do so -- I hope. Money is tight right now, though, and magnets are expensive....

A New-Old Set-up

Yesterday I used Krazy Glue to adhere some 39 ceramic magnets to the bottom of the old green hamster wheel -- this time without silicon steel and carpet tape underpinning. Unfortunately I have nine slots empty. The wheel turns until it gets to those slots, you see.

What will probably happen is that the wheel will not turn at all once I fill those slots. I also unfortunately painted the south poles red. It is the north poles that Howard Johnson said to use and the Krazy Glue won't work with the nail polish, so I will have to scrape or otherwise remove the nail polish before I turn them over to try again.

Krazy Glue dries faster than the Gorilla Super Glue, and Krazy Glue is more like the industrial type of super glue that I used in the 1970's when I worked in a factory, so I like the Krazy Glue better -- even though it seems to be super glue. Although, I was working with ceramic rather than neodymium magnets for the rotor this time.

I plan to fill the nine gaps and apply other stator mags before reversing the pole positions of the rotor magnets.

BTW, I think it is safe to plant now, even though May 15th - 20th is the safe date for this area. Next week is only supposed to drop to the low 50's.

I had to dig a ditch today, and tomorrow I need to fix the drainage on our dry well, plus I have planting to accomplish and a bit of weeding and lawn mowing, so these activities will delay my Howard Johnson magnet motor experiments for a few days, mostly. In between times I am trying to set up a work space for my Dremel, vices, and drill press. I might be moving books out of the workshop since I got one whole bookcase cleared out by selling books on Amazon for the last year and a half....

More pix to follow, if anyone cares....

HJ Experiments 2 and 3

Having an aluminum flywheel, I guess, is the defining principal for Experiment 3. Experiment 2 involves modifying magnets so they begin to approach the Howard Johnson model.

An aluminum pot lid sitting atop the plastic hamster wheel on the column and bushing of an old, defunct humidifier.

It did not work, even when it had all its magnets in place, with fewer gaps, but Mylow said to make gaps, so I did at the end, again. I tried his two sets of two with a middle gap, giving seven in the final group, but that didn't work either.

Mind you, I do not yet have proper magnets for the stator.

Here's the same set-up with the pan lid and hamster wheel upside down and off the bushing column. Please notice that I used sets of three disc magnets to attract the cylindrical magnets that are now upside down at the bottom.

Red coloring on magnets usually indicates the north pole for my rigs.

One half of a cylinder magnet with a central hole in it -- that I cut in half, giving 4 halves from two magnets -- sits atop the center of the hamster wheel. It stands up on its north edge, all on its own.

You can barely see a hint of red at the bottom of it. It is covered with plastic tape, not only to help protect it from oxidation, but also the tape helps remove the neodymium shavings from the cutting process.

From a different angle is a picture of this magnet below.

This is the round side, the other side being flat except for the half-hole at its center. You can see the red more clearly here.

The aluminum pan lid is now magnetically attractive, even at its center where there are no magnets. I doubt this effect will continue once the magnets are removed.

But the interesting thing to me here is that the half cylinder orients itself exactly the same as all the other magnets that are below and all around it. I would have thought it would go the opposite direction.

Also, the outside curve of the central magnet -- I thought -- is such that the magnetism should leave the magnet before getting to the farthest edge, but since it is standing up on its north edge, perfectly straight, I guess the magnetic flux lines are more complicated than I can fathom.

I am seriously now considering adding pieces of metal to the poles to help the flux lines become more concentrated as Howard Johnson was trying to accomplish. I have a couple different set-ups in mind, but those -- if they worked -- would be a precursor to casting small metal pieces rather than simply adding steel sheet metal or bending a hollow rod on its ends for fully cylindrical magnets such as are shown in the first picture.

Next Day: I filled the gaps again for the cylinder magnets, and dismantled the soft steel+carpet tape band around the plastic hamster wheel to see whether or not the metal band made a difference to the magnetic field. Not really, at least not at the center, where the half doughnut magnet stands on its north tippy toe.

That center geometry actually makes eminent sense since all the edge-placed magnets send their flux toward each other at the center. All like flux coming together makes a parallel region where they meet. In this case, shooting north to south in the opposite direction to the originating magnets' orientation, thus creating the perfect "holding region" for a similarly oriented magnet at the center.

The Push is On

I am committed and hot on the trail to duplicate Mylow's set-up so that I can start selling kits some day for other people to corroborate Mylow's set-up. However, I feel this morning that gravity plays an important role in the functioning of Mylow's set-up, which explains why my horizontally placed cylindrical magnets won't work.

Today I am about to "sacrifice" a pot lid made from aluminum. I will probably coat it first with packaging tape before using glue on it, though. The point of the above paragraph is that I do not believe Mylow's successful set-up is solely due to Howard Johnson's magnetic geometries, but rather, depends upon the unequal weight of the components which adds to the flywheel effect.

But we shall see, eventually.

Noon: Well, I see that Super Glue is not the way to go. At least Gorilla super glue dries too slowly. Now I have that gunk on my fingers, and am trying to get it off. Luckily I purchased some remover gel, but it doesn't work fast enough, either. Trying to glue magnets feels like those fairy tales where the damsel has to spin a roomful of straw into gold -- impossible.

So, I have now switched to putting disc magnets on the other side of the aluminum lid in order to hold the cylinders in place. This is not without hazards, too, but at least I do not have to wait for the super glue to dry. Probably I made a problem for myself by using packing tape to coat the aluminum first. This tape is completely non-porous and slick.

No wonder it took 30 years for Mylow to get anywhere, if he used glue. You cannot glue magnets that face the same way next to each other until the glue dries and holds on the first magnets that you put into place. Such a black hole for time, this is! Not to mention one's exposure to glue out-gassing while they dry. I hate chemical smells. I won't even paint pictures in oil for this reason. I am strictly a watercolor gal.

Cutting Magnets

Cutting magnets is not as difficult as I had imagined. Of course it helps that we got a workshop set-up when we bought our house. One beautiful vice makes all the difference to this project.

I purchased some cylindrical magnets on sale -- see my "Magnetism Geometries" page for the source -- and am proceeding to cut them in half. Both halves will have north and south pole tips which I will have to whittle down -- I suppose on a grinder -- to give the near knife edged poles that Howard Johnson's 1979 patent requires for his magnetic motor.

These magnets are much taller than I would have liked, but I cannot afford to buy any more magnets at this time, so these will have to suffice for this initial attempt to make Howard Johnson magnets.

One surprise is that the materials -- the filings from these magnets that I am cutting -- are flammable. Who knew? So now my motto is "Just Add Water." I cannot allow the magnets to get hot because that would negate their magnetic properties, so water prevents fire and loss of magnetism. I suppose when I get half-way through this first cut, I will have to put a spacer into the first cut and then turn the two magnets 180 degrees to cut from the other side. 

I am cutting straight across from pole to pole, which I found by putting the two cylinders together. They found their opposites for me. Cutting is not as difficult as I had imagined because the hack saw blade has fine teeth on it. The points of the blade have so far been all that have been in contact with the magnet, so the pull of the magnets on the blade has not made an overwhelmingly large drag. I imagine things will get tougher once I have gotten down where the whole height of the metal blade comes in contact with these two very strong magnets.

I am getting a workout, though. Maybe I will lose some weight in the process, after adding the muscle I will be getting in my arms. I wonder how many days this will take -- just this first stage? I have yet to decide how many HJ magnets I will get from these two, and whether to segment them before grinding, or segment them after grinding?

As near as I can tell, though, if I were to sell HJ magnets, they would be expensive. Economies of scale will have to wait til later, lol....

The aqua color is padding from a roll of camping gear that you roll out to sleep on the ground.

I like to paint the north poles of my magnets with bright red or pink nail polish.

So far I have made it almost half-way through these two cylindrical magnets that are made with a hole in the center.

I think I have to go get another hack-saw blade, though. The first blade is getting dull rather quickly, even though progress is slow due to having to keep the magnets cool at all times.

And then there is the little problem of turning the magnets over to do the other half of the sawing, plus filling the gap that I have already made so that when I clamp them together they won't collapse.

I wonder if rare earth is diatomaceous earth? That might explain why it is flammable. I wonder how you grow diatoms? Hmmmm. Maybe those are in plankton? I will have to do some more research. Oh joy!

One thing is certain. I will be testing these magnets for their HJ potential before making any more cuts after this one has been accomplished. The less work required to produce workable magnets, the cheaper the product will be to manufacture, unless demand for rare earth makes its price soar, knock wood.

Candidates for Deconstruction Experiments

One of my cylindrical magnets suffered damage from one of the many times these magnets have slammed together quickly because I was not concentrating on protecting them from this natural force. Neodymium magnets are very strong, and when brought near each other they exert overwhelming forces, either to rotate and then crash together, or to rotate and be stopped by some intervening material from crashing together. Mostly I situate my hands so they will hold the magnets apart, but after not dealing with the magnets for some period of time I forget to do this at first.

Anyway, one magnet has a deep gouge in its side so that I can see the material inside. The nickel alloy outer plating is missing and I can see, there, that the inside is made up of materials that have been compressed together, rather than simply "stirred" or blended together so that while cutting and grinding them the surfaces will more than likely be less than perfectly smooth, unless I can find some process to counteract the vagaries of the materials contained therein. Add to the inconsistent densities the forces that will be acting on my tools, vice-grips, and the magnets themselves due to magnetic pushes and pulls, and the task of modifying these magnets becomes quite challenging.

I hope to make a series of close-up photos showing my basic research into plumbing the physical depths of my cylinder magnet, both for readers and for myself in order to aid future cutting and grinding operations on these strong neodymium magnets.

I may also sacrifice a couple of my small, carbon-looking bar magnets that are suitable for the "track" magnets, be they stationary or rotating. Those were cheap magnets from Edmund Scientifics company which I might purchase more of.

Currently I an toying with ideas for making a very small HJ magnet motor on top of the second generator wheel that I got from WindStuffNow, but haven't yet assembled. I look forward to finding a way to pair up the two concepts of generating electricity and tapping into the geometrically powerful Howard Johnson arrangement of magnets.

I wish I could ask a physics professional how they would explain the Second Law of Thermodynamics vis a vis the simple event when two magnets are drawn together and both of them move. How do we detect the loss of energy, or rather, the expenditure of energy by the two magnets that have moved? Work was done because the magnets weighed something and they moved some measurable distance, yet neither neodymium magnet sustained a measurable loss of power? The event is also evidenced by the damage that one of the magnets sustained and that damage is permanent, but the damage does not always occur. Certainly neither magnet sustained a loss of power equivalent to the work that occurred during the event of the two magnets slamming together suddenly due to their attraction at a distance?


I had an array of 48 small magnets spread out over my homemade table in order to let them dry after painting the south sides of them with red nail polish. (I had been aiming for the north side to paint, but stuff happens.)  The table I use for magnetic experiments  is a 4 X 8 sheet of plywood painted to resemble a ping-pong table. It straddles two desks of differing heights.

One spot on the table kept flipping over my little magnet so that I could not paint it properly. WTF? Looking underneath I found two old speakers that we haven't used in years that I had used to level the plywood. Oh yeah! Speakers have magnets in them!

I do not believe that the presence of the speakers skewed the results on my past HJ experiments, but I can't be certain. Then my bearing is inside a fan motor that should definitely have magnets in it. It is time to clean house again -- that's for sure.

I wonder how thick the speaker magnets are? So, I am off on another project. I hope I can cut the speaker magnet so that it can be used as an HJ magnet, even if only a tiny one. I also planned to set up an experiment closer to Mylow's configuration but without the aluminum turntable. I think I might be able to get my magnets to "stand" upright like Mylow's by tucking them inside the hamster wheel with their sides attached to a perimeter band of silicon steel.

I know. Eddy currents can form in the band of silicon steel. Eddy currents in Mylow's set-up seem to me to be unlikely to help in the rotation because the stator magnet is too far away from the turntable to have much effect. I also know that the stator magnet can move the flux lines of the rotor magnets, and flux lines cutting through metal is all that is required to create eddy currents. Again, I am assuming that the number of flux lines actually moving through the aluminum is relatively small. I will be testing this hypothesis, too.

Later Note: This A.M. I saw the NOVA TV program about the sun. Magnetism sure works in mysterious ways. So I take back what I said about eddy currents, lol.

The speaker magnets are probably too thin to make HJ magnets from, however, if I cut them in half, then stack all four halves, perhaps the four layers would be thick enough. Most of my magnets are either round as in spherical and cylindrical, or too thin, as in discs, to make HJ magnets from them. It seems a shame to destroy speakers, but we have two boom boxes that come with tape and disc players....

Mylow's Guess

Mylow guesses that his first magnetic motor worked due to eddy currents, at least in the radio interview I gave a link for some entries back, at Free Energy Now, reported by PESWIKI. I think he could be correct in his guess, but I am inclined to view his success differently. If, in fact, there were no shenanigans going on in the video and his testimony, and from my observations of my own experiments, I believe his success depended more on the turntable being almost perfectly balanced on a low resistance bearing plus his slightly off balance arrangement of rotor magnets.

Mylow's turntable was made from aircraft aluminum which likely has good quality control for thickness, making it likely to be well balanced. My experiments gave me revolving of the wheel up until I place the final few rotor magnets to complete the circle, leading me to believe that being off balance is crucial to the rotation. His rearrangement of a few rotor magnets ended up being slightly asymmetrical, and I think that is the key. Of course, the low friction bearing is also necessary.

I will try to replicate his experiment but with a neodymium stator magnet that I will cut down from one that I get from a magnet manufacturer. See my "Magnetism Geometries" page in the left column of this blog for my links to that manufacturer.

The video and experimental magnet motor referred to above has a single circle of rotor magnets and a single stator magnet. Another magnetic motor video has multiple , narrowing circles of rotor magnets and two stator magnets. In this second magnet motor, the application of gravity can be seen as even more evident than in the first.

The stator magnets move up and down in the second. Mylow says they jump up when there is a gap in the rotor magnets -- of which there are two gaps. Ostensibly the stator magnets half jump up due to the south pole magnetism coming from the gap, making a repeating rocking motion since the stator magnets have both north and south poles facing downwards toward the turntable.

I guess that the jumping up of one side then causes the magnet to push harder when it returns to stasis with the rotating magnets. This gravity assist over the face of the flywheel effect -- inertia carrying the turntable past the gaps -- is more evident in the second magnet motor, perhaps because there are more magnets interacting in the second.

If there were no tricks in those videos and motors, then replicating Mylow's accomplishment but with neodymium stator magnets could give a longer lasting turning. Longer than 20 hours is a laudable goal, imho.
