Diamagnetic attraction motor

It is an interesting idea that I think you should try and see how it goes. One thing though. It could just be the way you've drawn it but geometry of the wedge will actually work against the motion of the spinning wheel. As the magnet passes further and further down the wedge more and more diamagnetism is acting upon it which will force it to travel back the way it came since that's the easiest path for the magnet to travel (remember energy likes to take the shortest route possible, no exceptions. The route ultimately depending on it's environment and the type of energy in question).

A rectangular piece of bismuth parallel with the face of the magnet on a spring would be a better shape I believe. Also you've got to remember the strength of diamagnetism is very weak, that said I don't want to immediately discount the idea so bite the bullet and try it.

Thanks for the push along Raui your block of bismuth does make more sence than the wedge idea.

Thinking along the same lines you could easily say that the weak magnetic repulsion from the bismuth would likely be equal to the reduction in "sticking" between magnets negating any marginal gain the design might have.

I do however prefer to do rather than talk and I will give it a shot in my spare time. If I get any interesting results I will be sure to share.

rather than using diamagnetic material, why not use something like mu-metal that has such a high permeability that it can cancel the repulsion of 2 opposing magnetic poles.

Consider this: if you had 1 magnet on the outside of the rotor, and one on the rotor, with like poles facing each other, they would repel each other when they started to line up. If you had (through some type of off-set gearing) a mu-metal (or something that outright blocks magnetic fields) shield pass between the two magnets as they were approaching each other, the repulsion could be eliminated/minimized. You could set it up so that just after the magnets aligned the shield moved out of the way, then you'd have the repulsion force to drive the motor.

Thanks for the input

I have a few designs that I am working on using magnetic sheilding that are along similar lines to what you suggest. My initial tests have shown me that there is little to gain using sheilding but I need to make my setup more rigid so that there is better energy transfer.

I will post results one I give it another proper try
