An electromagnet is characterised in that the core consists of at least two parts (1, 2) which are electrically insulated from one another. In this case, each part has an electrical connection (6), the one winding end (8) of the coil (7) which encloses the two parts (1, 2) of the core being conductively connected to one part (2), and the other winding end (9) being conductively connected to the other part. <IMAGE>
