Abstract
An electromagnetic actuator includes an electromagnet having a coil, which coil surrounds a pole core, and a magnet armature, which can be moved toward the pole core by the electromagnet, wherein the magnet armature has a bearing surface facing the pole core and the pole core has a correspondingly opposite counter surface. The bearing surface and/or the counter bearing surface has a layer that prevents direct contact of the bearing surface with the counter bearing surface and that causes damping of the approaching movement.
