Claims (1)

[Scope of utility model registration request] A coil is inserted between the magnetic poles of a roughly U-shaped iron core wrapped around it, and both ends corresponding to the magnetic poles are magnetized with the same polarity, and the center between the two magnetic poles is magnetized with a different polarity from both ends. A seesaw armature electromagnet consisting of a magnetized permanent magnet and a rectangular armature having a fulcrum in the center and swingably supported on the permanent magnet, which holds both ends of an iron core. An electromagnet structure characterized in that an insulating member for fixing the iron core is formed with a receiving part for positioning a permanent magnet at a predetermined distance downward from the magnetic pole surface of the iron core.
