ABSTRACT:
An electromagnet comprises a coil core of ferro-magnetic material having a coil wound around the core. The coil is supported by a bobbin. The coil core is elongated, and the winding of the coil surrounds the core in its longitudinal direction, so that a homogeneous magnetic field extending between the longitudinally running end surfaces of the coil core is obtained along the length of the whole coil core. A touch free influence of magnetic field controlled means, such as reed switches, positioned along the length of the coil at one of its long sides provided with a winding being obtained, so that for influencing, said means can take a position relative to the magnet within a considerable margin determined by the length of the long sides of the magnet.
