Abstract: The present invention relates to a method and an arrangement for determining the armature (1) position of an electromagnet. In the method the potential differences in the yoke (2) or in the armature (1), generated by a non-homogeneous eddy current distribution in the event of a deflection of the armature (1), are detected to determine the instantaneous armature (1) position relative to a reference position from these potential differences. For this purpose at least one voltage difference is measured between two measuring points on the yoke (2) or armature (1), or between one measuring point on the yoke (2) or armature (1) and a reference potential. The armature (1) position relative to a reference position on the electromagnet is then determined from this voltage difference. The method can be performed cost effectively, and can also easily be applied to existing electromagnets.
