Abstract

PURPOSE:To make attracting force high when a electromagnet is excited and to make efficiency excellent, by providing an auxiliary piece on at least one side of the end part of a yoke facing a first magnetic pole part, whose facing area is made small, and a second magnetic pole part, and forming a closed magnetic path comprising the auxiliary piece, the yoke and the second magnetic pole piece when a coil is excited. CONSTITUTION:A permanent magnet 3 is provided between first and second magnetic pole pieces 4 and 5 in a permanent magnet part 1. A yoke 8 has both end parts between first magnetic pole parts 6a and 6b and second magnetic pole parts 7a and 7b. A coil 9 is wound around the intermediate part of the yoke 8 in a coil part 2. One of the permanent magnet part 1 and the coil part 2 is constituted so as to move freely with regard to the other side. The area of the first magnetic pole part 6a facing the end part of the yoke 8 is made smaller than the second magnetic pole part 7a facing the first magnetic pole part 6a. In this polarized electromagnet, an auxiliary piece 12 is provided on at least one side of an end part 11a of the yoke 8 facing the first magnetic pole part 6a and the second magnetic pole part 7a. A closed magnetic path comprising the auxiliary piece 12, the yoke 8 and the second magnetic pole piece 5 is formed when the coil 9 is excited.
