Abstract
A contactless magnetic bearing between two members, not necessarily relatively rotatable, comprises at least one magnet on one member cooperating with two ferromagnetic parts on the other member to exert a stabilizing effect in the direction of one degree of freedom due to oppositely directed mgnetic fluxes in the two parts parallel to the direction of the degree of freedom. The destabilizing effect in a direction transverse to the direction of the one degree of freedom can be countered by a lateral bearing, preferably an active bearing whose coil is arranged in the magnetic field of the magnet or magnets.
