Claims

[Scope of utility model registration request]

(1) A fixed iron core consisting of two parallel sides and a central side connecting the centers of these two sides, a permanent magnet that is attached with a magnetic pole in contact with the center of one side of this fixed iron core and generates an attractive magnetic flux; A magnetic pole piece is attached to the other magnetic pole of the permanent magnet with a part thereof protruding outward, and is formed in a U-shape, with both leg ends supported on the other side of the fixed iron core. A movable iron piece is attached to be movable between one side of the fixed iron core and the magnetic pole piece, and a coil that generates winding canceling magnetic flux is provided on the central side, and the canceling magnetic flux generated by energizing this coil is attached to the movable iron piece. A polarized electromagnet device characterized by being configured to cancel magnetic flux attracted within an iron core.

(2) Utility Model Registration The device according to claim 1, characterized in that the bobbin around which the coil is wound is provided with a bag portion, and the permanent magnet and the magnetic pole piece are installed in the bag portion. Polar magnet device.
