Has anyone tried this?

Low-Q, if you were asking me to show a video, I don't have any, sorry.

Hi lwh,

Nice work, but I don't think your design is right.

I think this motor should be built with a male/female - push/pull structure.

Half the motor should attract and the other half should repel.  You need to use both sides of the torus!  The rotor should not be flat, but enter and exit the toroid opening on both sides like this:  0>I<0 

Good luck and nice work.

You might find some ideas to help you in the files section of my yahoogroup:

Suppose two magnets are held together in opposition(like north pole on north pole).
Is the force with which the two magnets push apart equal, or less than the force it took to actually put them in this position of opposition?

The same can be asked about attraction: Is the energy that can be generated from two magnets attracting each other equal, or less than the energy it will take to pull them back apart?

These spiral designs can be elusive. The work that is done by a magnet has to be "undone"(thats why you get sticky spots).
