A magnetic radial bearing and a magnetic bearing system for non-contact support of a rotor shaft are disclosed. The magnetic radial bearing for non-contact support of a rotor shaft includes a rotating-field machine stator with a plurality of stator slots distributed in a circumferential direction, and stator teeth with radial ends arranged between adjacent stator slots. The number of stator teeth is equal to the number of stator slots. A three-phase stator winding is wound around the stator slots for producing a rotating magnetic field. An axially extending permanent magnet in form of a strip or plate is arranged at the radial end of each stator tooth, wherein permanent magnets that are adjacently arranged in the circumferential direction have alternating opposing radial magnetization directions.
