[Scope of utility model registration request] It has a coil block in which a coil is wound around an iron core having magnetic poles on both sides and an intermediate magnetic pole, and a pair of armatures having free ends corresponding to the inner surfaces of the magnetic poles on both sides of the iron core and a permanent magnet interposed between the base ends. The armature block has an intermediate portion swingably supported by the intermediate magnetic pole of the iron core, and one armature is in contact with the intermediate magnetic pole and the other armature is open so as to form a closed magnetic path through the intermediate magnetic pole. A polarized electromagnet characterized in that the armature free ends are arranged so as to be separated and reversed within the inner surfaces of both magnetic poles.
