Abstract
This electromagnetic device includes: two movable parts movable in parallel or antiparallel to each other; and a stator core arranged with two surfaces thereof respectively opposed to the two movable parts. At least part of the stator core is formed by stacking thin sheets in a movable direction of the movable parts and is retained with tensile stress applied thereto in a direction parallel to the two surfaces opposed to the movable parts and perpendicular to the movable direction of the movable parts.
