Antifriction bearings include circumferential as well as axial flux paths that the flux of four identical-polarity magnetic poles follows about an annular stator having annular end-pieces that enables a square law reduction in rotor eddy current effects over the heretofore known magnetic bearings. In one embodiment, control coils alone provide magnetic suspension along orthogonal X, Y axes, and in another embodiment, combination control and bias coils cooperate to provide magnetic suspension along the orthogonal X, Y axes. The stator and rotor are preferably constituted, in part, of a lamination of high magnetic permeability material.
