Abstract
An electromagnet of the plunger type is disclosed which includes a plunger body and a guide for guiding the plunger body in its sliding movement. The plunger body is formed with a resin coat on the surface thereof which is brought into sliding contact with the guide, and the guide is formed with a resin at least in a portion thereof which is brought into sliding contact with the plunger body, so that in the electromagnet the magnetic resistance may be reduced and the sliding characteristics and the wear resisting property may be improved.
