[Scope of utility model registration request] An excitation coil is wound approximately at the center of the middle piece of the E-shaped core to form an electromagnetic block, and one end of two magnetic pieces is connected with a permanent magnet to form a U-shaped movable block.
The armature surfaces provided on the upper and lower surfaces of the other end of each magnetic piece and the armature surfaces provided on the upper and lower ends of the middle piece of the E-shaped core and the inner surfaces of the ends of the upper and lower side pieces are opposed to each other with appropriate gaps. An electromagnetic device in which a movable block and an electromagnetic block are combined, and by energizing the electromagnetic block, the opposing polarized surfaces of the movable block and the electromagnetic block are alternately separated, and the movable block is moved back and forth.
