Claim:
1. A radial magnetic bearing for magnetic support of a rotor, said radial magnetic bearing constructed in the form of a heteropolar bearing and comprising: a rotor; a stator having a magnetically-conductive stator element which is arranged in surrounding relationship to the rotor, said stator element having a side facing towards the rotor and having recesses running in an axial direction of the stator element, said recesses having a trapezoidal cross-section; coils generating magnetic fields to hold the rotor suspended in an air gap disposed between the rotor and the stator, said coils having electrical lines disposed in the recesses such that a free space remains in the recesses between the electrical lines and the air gap; and a magnetically-conductive filler element disposed in the free space, wherein the filler element is made up by s ferromagnetic element, said ferromagnetic element being iron and the filler element is configured for placement into the free space in the axial direction of the stator element, with the electrical lines terminating flush with the magnetically-conductive filler element and with the magnetically-conductive filler element terminating flush with the rotor-facing side of the stator element.
