ABSTRACT:
A device for converting magnetic force to mechanical force including a member having an axis about which it is rotatable, the member having a peripheral edge portion formed of a material that is effected by the presence of a magnetic force adjacent thereto, at least one magnetic member positioned adjacent the peripheral portion of the rotatable member to produce a magnetic coupling force therebetween, the peripheral portion of the rotatable member having a shape such that the magnetic coupling between the magnetic member and the peripheral portion of the rotatable member varies continuously as the rotatable member rotates.
