きい範囲での磁気吸引力ｇの特性が格段に優れている。However, according to this structure, the inclined concave portion 2 on the yoke 1 side is provided.
Since the upper surfaces of the inclined convex portions 4 of the movable iron piece 3 face each other, the contact area between the yoke 1 and the movable contact 3 during the suction operation becomes large, and the loss of magnetic resistance is reduced. Therefore, as shown in FIG. 3, the attraction characteristic graph S of the electromagnet according to the present invention is improved as compared with the conventional attraction characteristic graph T. In particular, the characteristic of the magnetic attraction force g in a large range of the operation stroke 1 (mm) of the movable iron piece 3 is remarkably excellent.
