したことを特徴とするソレノイド形電磁石。 An auxiliary yoke that protrudes outward from the main yoke that surrounds the coil is provided on the other end of the plunger, one end of which is in contact with the pole end surface that protrudes into the coil. When the coil is excited, the plunger and the auxiliary yoke are initially connected. The plunger does not move due to the attraction force acting between them, and then the magnetic flux passing through the auxiliary yoke becomes saturated, and the attraction force between the plunger and the main yoke is greater than the attraction force between the plunger and the auxiliary yoke. In the solenoid-type electromagnet configured such that the plunger starts to move when the plunger is bent, all or part of the auxiliary yoke is made of a magnetic material whose magnetization characteristic has a rectangular magnetization curve. electromagnet.
