硬度としたことを特徴とする電磁石。 A coil is wound around an iron core with a step formed at one end, and a substantially L-shaped yoke is caulked on the step side so that the magnetic pole surface of the iron core and the tip end surface of the yoke are flush with each other. In the electromagnet to be attached, the length from the stepped portion of the iron core to the magnetic pole surface is greater than or equal to the length from the inner surface of the iron core fixed portion of the yoke to the tip surface,
The electromagnet is further characterized in that the yoke has a relatively lower hardness than the iron core.
