ABSTRACT:
A mirror-moving system having a mirror mounted on a support member able to be repulsed by a superconductor, the mirror being suspended above a superconductive material and a ferromagnetic material around the outer periphery of the support member with a plurality of field coils positioned around the periphery of the ferromagnetic material, each of the field coils being independently operable to attract the ferromagnetic material to cause quick, frictionless movement of the mirror, depending upon which of the field coils is activated, by attraction of the ferromagnetic material to the activated field coil.
