Permanent magnet motor

I would assume that the  following device is just the result of the  un-winding of the string

I have also seen diagrams of this which related to the research/work regarding  siberian kolya .

But it would be a great basis for a some type of  magnetic-bearing ,  even if only for home use

I don't know, how can it be that way? Rotating like that should wind the thread, so it cannot rotate for so long. But i don't know. Sometimes, hanging a magnet from a thread in my hand like this, i like got an impression that it rotates infinitely around the bigger magnet. But whenever i fix the end of thread anywhere, it only rotates until it winds the thread. This, hanging from a thread, may be very deceptive though. The magnetic forces act in a weird way, and what happens just because of the initial kinetic energy, may look like moving because of some power. One thing, as much as i have seen, a magnet in that arrangement will never start to move from a standing position.

Anyway, this is no miracle there. Unless it starts from a static position, or rotates for an hour like this. Like hang something from a thread, without any magnet, make it to rotate, and you see that it can rotate quite a long.

About the magnetic bearings, again i think that the Mendocino bearings are the best for experiments. Very easy to make, from very ordinary magnets, and the pressure to the mechanical bearing is very small, it is rather just a balancing. And a kind of bearings which one can use, when one has no bearings. Mendocino bearings are something like on my picture above, plus the end of the pencil goes against some surface, Not exactly, but i think one gets the idea.

It's in orbit as you see the speed increase as the orbit lowers. (compare speed at start and end of video)

You put two disc magnets like on the drawing below. You really feel the rotating force. But the question is how to utilize that. Because the force down is a lot greater. Causes a lot of friction to the bearings, so that the rotating force cannot overcome that. Even with magnetic bearings it's hard to compensate the force down.

This may be just my subjective feeling. But you may try it and say whether you feel the same.

I tried it that way, on the picture below. This is actually a cigarette pack, the axis are made from paperclips (removed plastic from them and used pliers to bend them), and fixed with a mounting tape. No luck, no rotation. So the rotating force may be there, but it is evidently very small, so it is not possible to show it in any feasible way. I would say it rotated a bit, when the disc was slightly out of balance. What i can say though, when placing another disc magnet near that rotating disc magnet as shown in the previous post, and do it carefully so that it is exactly radial, then the rotating disc magnet did not move at all in the direction of its axis, but remained perfectly still. Just who may try experiments like that, so they know it can be done that way, yet it cannot be made to rotate.

Thus so far, only my field lines chain experiment https://archive.org/details/Flcm3 seems to provide any overunity. How to make friction so small that it would rotate continuously, if that can be done at all, is another question though.
