Abstract: The DC operated polarized electromagnet includes a spool around which an excitation coil is wound and that has a central opening, a plunger having first and second armatures, fitted individually, an outer yoke enclosing opposing side faces of the spool so as to attract the first armature, an inner yoke arranged on the inner side of the outer yoke so as to attract the second armature, and permanent magnets arranged between the outer yoke and the inner yoke, and reduces magnetoresistance by setting the thickness of the outer yoke thicker than the thickness of the inner yoke so that convergent magnetic flux in the plunger is diverted into the outer yoke.

When a current is applied to the at least one coil, the at least one coil is configured to reduce a magnetic flux of at least one permanent magnet in one direction and increase a magnetic flux of at least one permanent magnet in another direction. The movable armature moves in the direction of the increased magnetic flux.

Abstract: A plunger is formed of a soft magnetic material to have one end connected a regulation pin. A permanent magnet is affixed to a stationary portion to attract the plunger in a retreated direction. A coil generates a magnetic flux in an opposite direction of the permanent magnet to reduce a magneto attraction force, which attracts the plunger. A spring biases the regulation pin in an advanced direction. The spring applies a biasing force to the regulation pin to move the regulation pin in the advanced direction when electricity is supplied to the coil to reduce the magneto attraction force of the permanent magnet. A molded portion defines a magnet accommodation hole and a cover member covers the permanent magnet housed in the magnet accommodation hole. A magnetism detection unit is disposed on an opposite side of an inner surface of the cover from the permanent magnet.
