Claims

[Scope of utility model registration request]

(1) A U-shaped core, a permanent magnet that is attached with one of its magnetic poles in contact with the side of one leg of the U-shaped core and generates an attractive magnetic flux, and a permanent magnet that is attached to the other magnetic pole of this permanent magnet. a movable yoke whose one end is supported by the tip of the other leg of the U-shaped core and whose other end is attached to the yoke so as to be able to move toward and away from the yoke to form a part of the magnetic path for the magnetic flux to be attracted. Iron core and the U
and a coil attached to the other leg of the movable iron core that generates a canceling magnetic flux, and the canceling magnetic flux generated by energizing the coil cancels the attracted magnetic flux in the movable iron core. A polarized electromagnetic device.

(2) Utility Model Registration In the item described in claim 1, one leg of the U-shaped core is bent at a nearly right angle at the connecting part of the leg, and a coil is wound around this bent leg,
A polar electromagnet device characterized in that a notch is formed in the end face of the leg, and the movable iron core is supported by the notch.
