What if you could have a unipolar magnet?

[AquariuZ]

Hi AquariuZ,

I don't know how or why a unipolar magnet motor would work.

Please show a working unipolar magnet motor and or a unipolar magnet that is made without shielding.

Thanks for sharing

Noone has made a PMM with unipolar magnets because unipolar magnet officially do not exist and shielding, well if not done 100% correctly fails as well. If you block out ENTIRELY the flux of one polarity the task of creating a PMM becomes very simple.

More later, it is late.

What makes permanent magnet motors fail?

The flux duality. "Sticky points" Single polarity = no flux interference from the "other side"

Constant attraction / constant repulsion / constant acceleration until bearing limit.

Line ´em up and let ´em rip.

The cow magnet design is similar to my concept posted above. also you can use long normal bar magnets and mount on a wheel, all south poles facing the hub then the outer rim of the wheel will be for all intents and purposes comprised of unipolar north poles.

But monopoles won´t help, for example take two seperate monopole magnets. Each has N polarity. As they come together you have to work against repulsion, as they go apart the repulsion works for you but the net forces are zero.

I think some neat and tricky time variant effects will be needed for a PMM to work. If you can make the magnet just a little weaker while its fighting against rotation then net forces can be made non zero and it will self run.

Yucca, time will tell. I think it will work with a correct angle and in attraction mode not repulsion mode.

Appearantly the magnets deplete rapidly in repulsion mode for some reason (or so I was told)

Well, now you know where to get unipolar magnets for anyone interested.

I think someone here did forgot that a unipolar magnet is a uni-circular field. A monopole is actually no pole as the circular magnetic field cannot determind a polarity without a reference point outside it. Normally you can determind the polarity if the reference point is another circular magnetic field with a counter rotation - like you find in any magnet or electromagnet. Then you have an "enterance" and "exit" of the magnetic field, where the poles are determind in axis direction.

However a uni-circular field cannot exist alone. The limited extent of a possible unipolar magnet would force the magnetic flux to collapse as the field would look like a ball ot thread. That means the magnetic field would go in all directions within the same magnetic flux-sphere like the thread in the ball - and therfor it will collaps. You can try to wind up a magnetwire as you do with a ball of whool thread, and put current through it. That is a monopole, but there is no magnetic field.

So, the animal rectum monopole magnet is litteraly BS.

Nice. But even though it may encounter BS I do not think it is BS. 

I'm sure you saw the patent right? Easy enough tested if you have a flux meter...
