ELECTROMAGNET DEVICE AND ELECTROMAGNETIC RELAY

To reduce a leakage magnetic flux.SOLUTION: An electromagnet device 3 comprises an electric magnet 5, an armature 7, a permanent magnet 9, and an auxiliary yoke Y1. The electric magnet 5 includes a coil 50 and a yoke 52. One magnetic pole of the permanent magnet 9 faces the armature 7. The auxiliary yoke Y1 has a first face Y11 and a second face Y12. The first face Y11 faces the other magnetic pole of the permanent magnet 9 and crosses a magnetic pole direction of the permanent magnet 9. The second face Y12 turns to the side of the yoke 52. When the electric magnet 5 is excited, the armature 7 moves in a direction of becoming closer to the yoke 52 or in a direction of becoming more distant from the yoke. The second face Y12 of the auxiliary yoke Y1 faces the yoke 52 at least in a partial range of a movable range in which the armature 7 moves depending on excitation of the electric magnet 5.SELECTED DRAWING: Figure 9 【課題】漏れ磁束の低減を図ること。【解決手段】電磁石装置３は、電磁石５と接極子７と永久磁石９と補助ヨークＹ１とを備える。電磁石５は、コイル５０及び継鉄５２を有する。永久磁石９において、一方の磁極が接極子７に対向する。補助ヨークＹ１は、第１面Ｙ１１及び第２面Ｙ１２を有する。第１面Ｙ１１は、永久磁石９の他方の磁極と対向しかつ永久磁石９の磁極方向と交差する。第２面Ｙ１２は、継鉄５２の側を向く。接極子７は、電磁石５が励磁されると、継鉄５２に近づく向き又は遠ざかる向きに移動する。補助ヨークＹ１の第２面Ｙ１２は、接極子７が電磁石５の励磁に応じて移動する可動範囲のうち少なくとも一部の範囲において、継鉄５２と対向する。【選択図】図９
