Abstract

PURPOSE: To make the absorbing surface of an electromagnet steady and reduce the fluctuation of operation characteristics by forming a very hard wear durable layer on the absorbing surface.
CONSTITUTION: On the absorbing surface of a stationary iron core 1 and a movable iron core 4, very hard electroless nickel plating layers 11 and 12 are formed. To the movable iron core 4, a shaft 8 to transmit the motion of the movable iron core 4 is attached oscillatably.
