Abstract
An electromagnet device is assembled to, e.g., an electromagnetic relay. This device comprises a movable assembly which is swingably supported and a core in which a coil is wound around a part thereof. The movable assembly has two magnetic plates arranged so as to face each other with a distance and one permanent magnet arranged between those magnetic plates. Each magnetic plate has operating portions at both end portions thereof in which magnetic poles appear due to the permanent magnet. The core has two end portions which are arranged so as to respectively face the operating portions of the magnetic plates. At least one of the operating portions which faces at least one of the end portions of the core is formed at the edge surface of the magnetic plate.
