Abstract
A magnetic bearing for active magnetic centering, on at least one centering axis perpendicular to a reference axis, a first body mobile at least on this centering axis relative to a second body includes at least one magnetized member and at least one coil wound around a ferromagnetic core substantially parallel to the reference axis and carried by the second body. Two parallel ferromagnetic plates perpendicular to the reference axis are attached to the core on respective opposite sides of the coil and have transversely oriented edges opposite the airgaps. The core is attached to the edges of the parallel plates.
