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

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

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.

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

Look at the flux lines. There is four loops. One pole at the ends and the other pole in the middle. There is a magnetic closed loop, so this is just a doubble regular magnet. One magnet in each end where the same pole is facing outwards. The poles pointing towards eachother in the middle force the fluxlines to excape out to the sides and close the flux loop at each ends. Looks like it on one of the drawings anyway. So this is most probably no monopole, but a doubble dipole. Not very common, but not rare either.

According to wikipedia:
"Magnetic pole model: Although for many purposes it is convenient to think of a magnet as having distinct north and south magnetic poles, the concept of poles should not be taken literally: it is merely a way of referring to the two different ends of a magnet. The magnet does not have distinct "north" or "south" particles on opposing sides." http://en.wikipedia.org/wiki/Magnet (http://en.wikipedia.org/wiki/Magnet)
I think a common magnet is already a monopole. There are no distinct north and south poles as wikipedia suggested. You have a force that is both leaving and returning to the magnet. The same force that leaves the magnet, will also return to the magnet. We refer to the south and north poles in order to distinguish between the force leaving or returning to and from the magnet. This force has the same properties when it is moving away from the magnet as it does when it is returning to the magnet.
There is only one thing that makes this force return to the magnet, and that is the aether moving in an orbital path due to the electrons moving in an orbital path with their spins aligned inside the magnet. Electrons moving cause the aether to move. Likewise, when you move the aether, it will move the electrons. Physics recognize this aether as virtual particles and is also known as the magnetic field of flux. Anytime you follow the same orbital path, you will always return and leave from any point along that orbital path.
There is no need to complicate this more than it needs to be.

You can go on alibaba.com. There are lots of unipolar magnet suppliers.
http://www.alibaba.com/showroom/single-pole-magnet.html
I am puzzled by the price. $0.01 means a PENNY.
Can anybody explain the pricing?
It's best to contact the supplier and see if you can order small quantities. Most suppliers are very accomodating.
Regards
sorry to disappoint you,
In Alibaba the translations Chinese-English are misleading.
They write "single pole" and also "monopole, meaning that the magnet has only one pole in each face, as they also manufacture magnets with many poles per face. (e.g. Axially oriented in segments)
See at mid page

Hi,
I live in Asia.The price of magnet is indeed cheap in China.I think they are the main global supplier around 90% for neodymium.
Like wise for Lithium it's also around 90%.
