Permanent magnet motor

[Jim36]

Ayeaye,

See link to video with circular magnetic field, you can see that it doesn't interact with the metal paper clip once the circle is made. True it could be fake (doesn't look it)  https://www.youtube.com/watch?v=LTq1VNMyLYQ&feature=youtu.be

The price for these magnets are high because they have never been made by the factory before, the magnets themselves cost $37.50 each but the tooling required to make them costs $300 (for the first one only)  then shipping to the uk $60. Once the tool has been made they should only cost $37.50 from that supplier, so this isn't hugely expensive.

I have done some experiments myself with magnets, I will still attempt some of your experiments too to see if I see OU.

Phoneboy,

The squirrel cage should work, as this is electricity passing through several conductors which has already been proven with the standard homopolar motor, I'm trying to provide the same effect but without the flow of electricity.

Yes the crushed neodymium did lose a lot of strength but was still strong enough to experiment with. What was your idea for a motor? Always good to share inspiration!

Jim36,

About that video, i don't understand russian at all. He said that vector field consists of two components, rotor and divergence. In magnetic fields, divergence is completely ignored, but it is 30% of the magnetic field. It appears when magnets that attract each other are completely together, the vector is on the line between the magnets. Doesn't attract iron objects, but repulses another divergence field and electric current. When the poles of two magnets are near each other, in the area between the magnets they don't attract an iron object, but near that area they do.

He didn't say much about the material of the ring magnets he used, other than that they were metal, that is not ferrite, and magnets which they used a very long time ago. So not clear whether that magnet is iron or alnico. He put the ring magnets to oven, and heated them to 900 celsius, so they lost their magnetic properties. Then he magnetized the halves, by wrapping a coil around them (like a coil on a solenoid core), and discharging 300 volts through the coil from the capacitors, through a welding fuse. When putting these halves together, this ring magnet did not attract a paperclip. He also magnetized a whole ring magnet that way, then split it, and the properties were the same.

This resembles the cores of some transformers. They are essentially magnetized the same way. After the current is turned off, the bar which closes the core, sometimes remains attracted very strongly to the rest of the core, for many hours. Which means that the flux remains inside. What are the magnetic properties of the core in that state, i don't know.

What concerns my experiment, this one https://archive.org/details/Flcm3 , then this is a chain of magnets, the same which supposed to form a circular field, when the magnets were next to each other. The reason is the same, most of the field lines between the magnets go from pole to pole, and thus less go outside, causing what you may call a leakage of the flux. This causes asymmetry of the field at each pole, and overunity is caused by that asymmetry, i described it more thoroughly in another thread here. It looks like though that it provides the most overunity when the magnets are weak, 5 x 5 x 3 mm ceramic, and at some distance from each other. This experiment may also be done with four 7 x 7 x 5 mm ceramic magnets which one can buy more easily, but with somewhat worse results.

What is it what i talked about before here, a divergence force? I'm not sure that it is there, but then i'm also not sure that it is not. So i would prefer to omit that.

To see if I see OU, You can never see OU, It's endless, it's infinite.
How could you ever see the end?
I like what your saying though, makes sense to me.

Thank you Shylo.

I forgot to say. He said that this ring magnet which he magnetized as a whole, and later split, was from an old loudspeaker. By the texture of the metal from where it was cut, it looks like alnico, but may be iron or some other alloy.

Yes this didn't look like a fake. There is no way to prove in a video that something is not fake, but it was not likely, or then it was very well made.

Anyway, ring magnets from some old loudspeakers, demagnetize them, and then magnetize them in a circular way, this seems to be the best way to achieve a circular field. I guess for that the magnet shouldn't be magnetized very strongly, as this may increase the undesired interactions and distort the field. Also maybe the ring magnet has to be thick, though not sure. Most horseshoe magnets have additional poles, so the question is how to avoid that.

A ring magnet from an old loudspeaker, magnetized in a circular way. Make it to rotate, bearings in the middle, and put a pole of another magnet near it. When the field is really circular, the ring magnet starts to rotate. This is all what is necessary for a permanent magnet motor. If the field is really circular, that is. This video gives some hope, plus the things seen or heard that some have already made such devices.

Capacitors, i guess he charged capacitors, and put them in series, to get higher voltage for magnetization.

Interesting why he didn't try the interaction of two of these ring magnets. If  that theory of the other component of a magnetic field were true, the circularly magnetized ring magnets had to repulse each other, when put near each other with their flat surfaces.

Ring magnet, yes, has to be ring magnet, because it's the easiest to wind a coil on it to magnetize it in a circular way.

The only way by now i think a continuously rotating permanent magnet motor is possible.

The images below are from that video, a circularly magnetized old speaker magnet (iron or alnico) does not attract a paper clip, but the same magnet does, when cut to half.

About demagnetizing a metal magnet, what can i think. The temperature of a gas flame is said to be approximately 2000 celsius, 3000 f i guess. If there is no gas flame, maybe putting it on a burning charcoal is enough. It supposed to be demagnetized, that is the temperature is some 900 c, when it glows clearly red. Maybe it can also be demagnetized electrically, when magnetizing it in an opposite direction, but i'm not exactly sure in that.
