What if you could have a unipolar magnet?

[AquariuZ]

A magnet that has single polarity flux?
Any strength. Any polarity.
Do you think you can make a permanent magnet motor then? Good.

I have got news for you: It exists.

Convince me and I will tell.

"They" are listening so get them before they wind up on some list which prohibits sales to individuals.

Interesting idea, I think I know of one way to do it:

A hollow sphere, for example, inside diameter 1cm, outside diameter 2cm. The material is magnetised throughout the entire wall thickness. The inside will contain a hidden pole with great flux density at the spheres centre, the outer surface will be unipolar.

An ovoid construction would make the outside unipolar field concentrate at the tips.

Actual contruction and magnetisation would probably require it to be made in two halves and then accurately faced and bonded to prevent flux leakage.

But I don´t see how it could help with building a PMM.

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.

I cannot keep a secret anyway

US Patent 7289011 Oct. 30m 2007 ANIMAL MAGNET PILLS HAVING SINGLE POLARITY (Attached)

A patent which contains an improved version of an animal magnet to battle "hardware disease"

The magnets have a selectable single polarity.

You can order them right here: http://www.animalsupplyintl.com/sheep_goat_products.html

Ships in boxes of 25 pcs.

Now scoot along and build your engines. Forget shielding, just use these... (no not in there!)

I know I am... How about a dual cylinder, outside static north polarity, inside rotor with angled south polarity.

Zoooom.

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
