Claims

[Scope of utility model registration request]

An electromagnetic block consisting of an intermediate magnet wound with a coil, a yoke having magnetic poles on both sides arranged in parallel on both sides of the intermediate magnetic pole, and a pair of magnetic pieces each having one end interposed in a gap formed by the intermediate magnetic pole and the magnetic poles on both sides. and a permanent magnet block having a permanent magnet sandwiched between the magnetic pieces, each having an armature swingably supported at one end of the pair of magnetic pieces, and intermediate magnetic poles facing on both sides of the armature. A polarized electromagnet characterized by having a step between the surface and both magnetic pole surfaces.
