Claims

[Claims for Utility Model Registration] (1) An electromagnetic block having an iron core around which a coil is wound and a magnetic pole part formed at at least one end, and two magnetic pieces that magnetize a permanent magnet. In an electromagnet device, the permanent magnet block is combined with the electromagnet block so that the two magnetic pieces sandwich the magnetic pole part of the iron core from both sides in the direction. An electromagnet device in which a notch is provided on one side, and a gap is formed in one side of a magnetic circuit formed on both sides of the magnetic pole part. (2) The electromagnetic block has an iron core in a C-shaped planar yoke, making the overall shape roughly E-shaped, and has a central magnetic pole section at the free end of the iron core, and opposing magnetic pole sections at both ends of the yoke that are opposite to each other across the central magnetic pole section. However, the permanent magnet block has a U-shape in which two pieces of magnetic material sandwich the permanent magnet from both sides in the direction of magnetization, and the ends of the two pieces of magnetic material are connected to the center magnetic pole part of the electromagnetic block. The electromagnetic device according to claim 1, which is combined with an electromagnetic block so as to be inserted into two gaps formed by the magnetic pole portion and the opposing magnetic pole portion. (3) The electromagnet device according to claim 1 or 2, in which the permanent magnet block rotates forward and backward about an axis on the opposite side to the electromagnet block side.
