Abstract
An electromagnetic motor constituted by a movable member, a flexible support member, a first fixed magnetic pole, and a second fixed magnetic pole. The movable member is magnetized to form N and S poles on opposing surfaces. One end of the flexible support member is connected to the movable member, and the other end thereof is connected to a base. The first fixed magnetic pole is so arranged as to apply a magnetic force in a direction parallel to the N and S poles of the movable member. The second fixed magnetic pole is so arranged as to apply a magnetic force in a direction perpendicular to the N and S poles of the movable member.
