    摘要: A magnetic rail brake, particularly an eddy current brake for rail vehicles, has at least one exciter coil which comprises a coil around a pole core as well as a device for holding the coil and/or for the protection against outside environmental influences. The pole core and/or protection device are composed of individual components which are at least largely electrically insulated with respect to one another.
