摘要： The present invention provides an improvement for noise suppression, in an electromagnet constructed of the parts including a yoke, a fixed iron core (2) fixed relative to the yoke, a movable iron core (4) capable of being attracted toward and coming apart from the fixed iron core and a coiled wire wound around the magnetic path formed of the yoke, fixed iron core and movable iron core which serves to attract the movable iron core toward the fixed iron core by means of the magnetic flux induced by passing an electric current therethrough, which comprises dividing either one of the fixed iron core and the movable iron core into a body member (2b) and an end-surface member (2a), at which the fixed and movable iron cores are contacted with each other, providing an elastic insert member (6) between the body member and the end-surface member of the iron core in such a manner as not to interrupt the path of the magnetic flux and, optionally, providing a spring means which urges a stem supporting the end-surface member in such a manner that the end-surface member is pressed against the elastic insert member with a predentermined pressure.
