Zusammenfassung: | An electromagnetic apparatus (105) comprises a magnetic core (135) having a longitudinal axis (137) and a coil former (128) that is circumferentially disposed around the magnetic core (135) and has at least one receiving region (142) for receiving at least one coil winding (141) of a coil (140), wherein the receiving region (142) is formed by at least one wall (129) of coil former material (134), said wall having a first portion (131) extending in the direction of the longitudinal axis (137) of the magnetic core (135) and at least one second portion (132) extending transversely to the longitudinal axis (137) of the magnetic core (135). The magnetic core (135) has a circumferential fastening portion (600) which has a tooth-like contour (601) in cross-section along the longitudinal axis (137) of the magnetic core (135) and is interlocked with the coil former material (134) of the coil former (128) by displacement of coil former material (134) in such a way that the magnetic core (135) is held on the coil former (128) by the circumferential fastening portion (600). |
