ABSTRACT:
A magnetic bar includes a magnetized core extending along a median line between two parallel polepieces extending along the magnetized core transversely to its permanent magnetization. The magnetized core embodies, substantially along the median line, a discontinuous succession of identical separate magnets. The magnetic bar can be used in the manufacture of magnetic bearings and thrust bearings.
