Abstract

PURPOSE:To obtain a polarized electromagnet characterized by high attracting force when the magnet is excited and excellent efficiency, by providing an auxiliary piece on at least one side of a magnetic poles and counter magnetic pole parts, and forming a closed magnetic path comprising the auxiliary piece, a magnetic core and one yoke when a coil is excited. CONSTITUTION:A coil 6 is wound around a magnetic core 5, in which one end is made to be a magnetic pole part 3 and the other end is made to be a linking part 4. A coil part 1 has a pair of yokes 9 and 10, in which one-end parts are linked to the linking part 4 and the other end parts are made to be counter magnetic parts 7 and 8. A permanent magnet 13 is provided between a pair of magnetic pole pieces 11 and 12. The permanent magnet 3 is provided in a permanent magnet part 2. Either of the permanent magnet part 2 or the coil part 3 is constituted so as to move in the facing direction of the counter magnetic pole parts 7 and 8 freely. The facing area of one counter magnetic pole part 7 is made smaller than the other counter magnetic pole part 8. In this polarized electromagnet, an auxiliary piece 14 is provided on at least one side of the magnetic pole pieces 11 and 12 and the counter magnetic pole parts 7 and 8. A closed magnetic path comprising the auxiliary piece 14, the magnetic core 5 and one of the yokes 10 is formed when the coil 6 is excited.
