Permanent magnet motor

[ayeaye]

One might just punch out some ring magnets from a rubber magnetic strip and then magnetize them by rotating them between two neodymium magnets.
Sounds a bit easier.

If you want to try it, sure do. I have nothing against experiments. I think it will not work, but then i may be wrong.

Hi Ayeaye,

You can emulate a circular field in a ferromagnetic tube by using two magnets with poles flipped next to each other.

Hi DreamThinkBuild,

Thanks, great. I can make a cube out of 8 of my small rectangular magnets, which would be similar to that inside the tube. But i don't have a ferromagnetic tube. I have nothing ferromagnetic with the shape of tube, that is. Maybe that idea together with that rubber magnet idea by Lumen may work. If it is possible to demagnetize a magnet tape, or magnetize it circularly, then it may serve as a ferromagnetic tube. But this is just what i happened to think when reading this thread again, i'm not sure in that at all.

I don't say at all that it will not work, and i don't want to discourage anyone from experimenting. But the problem with that, i think, is this. A ferromegnetic tube, if it is thin, it has no effect whatsoever. But when it is thick, more than 10 mm or such, then it effectively screens the inner magnets from the outside magnet. What a ferromagnetic material does i think, is that it takes the field lines into itself, and thereby screens them for anything outside. So inside the wall of that tube there likely will be a quite circular field, maybe also somewhat outside the tube, but there it may be much too weak. But then, a positive force strong enough to overcome the friction, is all what the problem is about.

This topic seems to interest many, but then no one seems to have a proper means to really try it, such as a welding transformer. People used to think permanent magnet motors are easier to make, than other overunity devices. Maybe right about just showing overunity, like my experiment https://archive.org/details/Flcm3 , but what concerns a real continuous rotation, they may need much more resources. Maybe after all, solid state devices with a coil like this https://archive.org/details/ndischarge are much easier to make by people with limited resources, than permanent magnet motors.

I think that if one could magnetize in a circular path, then the field might be fully contained within the magnet.
If there was any field leakage it would diverge away and no longer be circular.

That doesn't mean that this could not work as there could be some tendency to divert an incoming field in the same manner as a current carrying conductor.

The rubber magnet rings might work well because they magnetize easily and could be stacked to simulate a conductor with current.
If the working field was weak enough to prevent them form re-magnetizing they might work as a simple test.

Sorry for no activity, been working lots,

Yes I see what you are saying aye aye, regarding magnetising materials requires very high current, I still haven't had chance to experiment with re-magnetising a loud speaker magnet. I know that usually high current is required but there was an interesting post put on this thread with a video from Jason Verbelli showing 'Perpetual Magnetic Current' he turned Steel into a permanent magnet with low current, though I don't know the details of the steel used as this may be explained by normal physics if it has a relatively low cocervicity.

As for a circular magnetic fields, if the material is magnetised in this way a few factors will minimise flux leakage or extra poles as you mention, the surface of the material needs to be quite smooth, I found this out when I made my own circular magnet which had dimples in it, these areas had flux / poles in the air. Also magnetic flux follows the easiest path (low reluctance) air has a high reluctance, so if the tubes are made well enough I think flux leakage/poles shouldn't be real problem. you mentioned the flux is kept within the material so an external field will ignore the flux inside the material, this is not the case the external field will interact with any field or any substance appropriately, if this didn't happen then a new discovery in science has been found at least!

Ayeaye, this is not the only project i'm working on as I'm also working on a new type of transformer (I've done about 1 years experimenting with coils and custom transformer geometries) this motor will hopefully spin a generator to power the transformer, the transformer design is such that the secondary doesn't create back EMF / MMF so to tap from the ether. Not much torque will be required from the motor. This is all hypothetical obviously but I have come across some strange phenomena which has pointed me to do this. It is too early to post the work here as there is a lot of detail, but I am passing the information to another trusted group so if it works I'm not the only holder of the information, this is why i'm posting the permanent magnet homopolar motor here as it is has much less detail. I've actually purchased the circular tube magnets from a manufacture so will be working on building the motor ready for when they turn up. They believe that the magnets can be made to this degree, I suppose I will find out soon enough.
