Permanent magnet motor

[Jim36]

Webby,
Great video thanks, I've watched some of JV's stuff he's doing great things! The PMH is very interesting and I've never seen that winding technique. This could be something done with a laptop power supply EMI ferrite tube, though I don't know if the ferrite material will produce the same effect? Something I could try out.

Ayeaye,
Call it the homopolar 'permanent' magnet motor? Anyway that can be taken care of if it works. I will do further investigating before building a prototype and post on here the results.

Jim36,

Fleming's rules are about induction of magnetic field from electrostatic field, and vice versa, they are not about interaction between magnetic fields. Yet now i'm not sure that your original design would not work. And this is because something new which i maybe found about magnetic fields.

This is only how it seems to me, based on trying things with my i hope sensible hands, it is no way conclusive. It looks like that a cylinder magnet rotates around its axis, when another cylinder magnet (stator) is placed near it with the same poles facing each other, as shown on the drawing below. The upper drawing shows the directions of force to the field lines, can it be called some kind of right hand rule?

I couldn't make such device, because i have no bearings or anything, to make anything such to rotate. The rotating force was quite noticeable, as much i could feel by hand. I used 10 10mm ceramic disc magnets and 10 25mm ceramic disc magnets, all 5mm thick, to make these cylinder magnets.

The magnet hanging from the thread and rotating around the other magnet, as shown on the drawing right below, seems to work exactly on the same principle. I think i have seen this experiment in one video, though nothing was said about magnets or their polarity, and the thread was held by hand. Which made the experiment not valid, because everything can be done with a slight movements of hand, and thus no one has taken such things seriously, at best it has been seen as a toy.

I hanged the thread from my lamp, so i didn't hold it in hand. But the hanging magnet seemed to try to always face the other magnet with the same side. This twisted the thread and finally it stopped. I don't know how to prevent the thread from twisting.

So i think this should be tested, if there are any mechanical means to make things to rotate. Because if it really provides a continuous rotation, then it would be something really great, no doubt. But if and only if such test would be positive, of course. Seems too good to be true i know, but then this necessarily doesn't mean that it cannot be true. And the rotating force has to be enough for continuous rotation, for it to be any worth.

I would call this design a rotating pole motor or a revolving pole motor. It is homopolar. As this thread is in the subforum of theories of overunity, then it is appropriate for the discussion of general theory of overunity in magnet motors, i think.

Errata: The left magnet on the top view below should rotate clockwise. The hanging magnet should rotate counter-clockwise.

Like that?

Small ceramic bearings are tougher than steel ones and are quite common these days.

Thank you Mscoffman, very important information.

Theory in case if it works. If there is a repulsion force to a pole, then the direction of the force to the field line affected by the repulsion, is 90 degrees from the direction of the field line, considering its direction, when looking towards the magnet to the direction of the axis of the magnet. This is in addition to the other forces known in the magnetic field. Weird. And this is all the explanation there is.

Or maybe Jim36 or anyone else can explain it more.
