る電磁石装置。 An electromagnetic block includes a central magnetic pole part and an opposing magnetic pole part magnetically connected to the central magnetic pole part, and the central magnetic pole part and the opposing magnetic pole part have different polarities when a coil is energized, and two pieces of magnetic material move a permanent magnet to the magnet block. The armature block is sandwiched from both ends in the magnetization direction, and the same side ends of the two magnetic pieces are inserted into the gap between the central magnetic pole part and the opposing magnetic pole part, and the armature block is permanently connected to the coil. In an electromagnetic device in which an armature block is moved forward and backward in parallel by the action of a magnet, the maximum attractive force exerted on the armature block by the opposing magnetic pole parts and the maximum attractive force exerted on the armature block by the central magnetic pole part An electromagnet device characterized in that the direction in which the combined attractive force acts substantially coincides with the direction of forward and reverse parallel movement of the armature block.
