An electromagnetic device includes a coil, a fixed member, a movable member configured to reciprocate to separate from the fixed member by a predetermined gap when a current applied to the coil is stopped and move to the fixed member by an attractive force when the current is applied to the coil, and a permanent magnet. The permanent magnet is arranged at a position adjacent to the gap and separated from the fixed member and the movable member with a space interposed therebetween. A direction of a second magnetic flux generated by the permanent magnet conforms to a direction of a first magnetic flux generated between the respective opposed surfaces of the fixed member and the movable member when the current is applied to the coil.
