Abstract

The invention relates to an eddy current brake (1) with a stator (5) and a rotor (8) that is magnetised when it rotates about an axis of rotation relative to the stator (5). The invention is characterised in that the stator (5) and the rotor (8) are arranged and designed in such a way that the rotor (8) is magnetised in a radial direction when it rotates about its axis of rotation relative to the stator (5).
