Claims

[Scope of Claim for Utility Model Registration] (1) A yoke is provided at one end of the core, and this yoke extends opposite to the core, and its tip faces toward the free end of the core and is divided into left and right halves, sandwiching a notch. An electromagnetic block in which each of the opposing protrusions serves as an opposing magnetic pole part and the free end of the iron core serves as a magnetic pole part, and at least one permanent magnet and two opposing magnets sandwiching the permanent magnet from both ends in the magnetization direction. and a contactor block consisting of body pieces, the two magnetic pieces of the armature block being assembled into the notch portion, and the two blocks being assembled so that the magnetic pole portion of the iron core is inserted into the armature block, The armature block is configured to move in the forward and reverse directions within the notch by the action of a coil and a permanent magnet, and the iron core is flat so that the thickness in the direction perpendicular to the magnetic piece is thinner. An electromagnet device characterized in that the armature block does not protrude outside the yoke. (2) The yoke extends opposite to one side of the iron core, and the armature block is formed in a U-shape by sandwiching one permanent magnet from both ends in the direction of magnetization, with the ends of the two magnetic pieces on the same side. An electromagnetic device according to claim 1, which has now been registered as a utility model. (3) The yoke extends opposite to the iron core with the iron core in between, and the armature block has two magnetic pieces sandwiching two permanent magnets from both ends in the same magnetization direction. The electromagnetic device according to claim 1 of the utility model registration claim, which is shaped like a letter. (4) The opposing magnetic pole part that one of the two magnetic material pieces faces is shorter in length than the opposing magnetic pole part that the other one faces. The electromagnetic device according to any one of the above. (5) The electromagnetic device according to any one of claims 1 to 4, wherein one of the two magnetic pieces has a cutout hole.
