ABSTRACT:
A polarized electromagnetic device is disclosed having a generally I-shaped magnetic core member, a coil which is wound on the center portion of the core member, a pair of permanent magnets which are arranged in parallel with and outside of the respective end portions of the core member, and mutually confronting first and second armature plate members which are joined together through the pair of permanent magnets, with each magnet at the opposite end portions of the armature plate members in order to provide a spacing for accommodating the core member between the armature plate members, and consequently leaving a gap for relative movement therein. The core member and armature plate members are supported to be swingable relative to each other for movement about a center transverse axis of the center portion of the core member.
