Abstract

A safety apparatus for avoiding a possible fire risk in an operating magnet supplied with electric current has at least one coil former (14) arranged in a housing (76, 82). A coil winding (16) is fitted on the coil former and has an operating part (20, 36) at least partially guided in the coil former (14). At least parts of the operating magnet are equipped with active and/or passive safety mechanisms of the apparatus to effectively counteract the risk of fire. The safety mechanisms are no longer arranged remote from the actual event, for example in the form of a fuse in the electrical supply circuit, but rather are directly at the location of the event where the possible fire or scorching situation can directly occur.
