An electromagnet device has a movable iron piece having an end that is operable to contact and separate to and from a magnetic pole portion of an iron core. The movable iron piece rotates based on magnetization and demagnetization of a coil wound around the iron core. A tapered surface is formed on at least one end of an attraction surface of the movable iron piece, which attracts to and separates from the magnetic pole portion of the iron core. At least one contacting portion that is in flush with and continuous to the attraction surface and in contact with the magnetic pole portion of the iron core is arranged in a projecting manner on the tapered surface.

A magnetically sensitive element is integrated with an operation controlling element by film-forming process or bonding of film-shaped bodies. The operation controlling element is formed as a single layer or multilayers and contains a permanent magnet or a magnetic circuit forming member. A pickup coil may also be integrated thereto. The magnetically sensitive element is a magnetic element in which a giant Barkhausen jump phenomenon appears.

A light irradiator used as a laser annealing apparatus is provided which includes a controller (9) which controls a solid-state laser (4) to make pulse-on operation by detecting that the angle of rotation of a rotating shaft (7a) becomes +β after the rotating direction of the rotating shaft (7a) changes from clockwise to counterclockwise and then make pulse-off operation by detecting that the angle of rotation become −β, while controlling the solid-state laser (4) to make the pulse-on operation by detecting that the angle of rotation becomes −β after the rotating direction changes from counterclockwise to clockwise and then make the pulse-off operation by detecting that the angle of rotation becomes +β. Further, the controller (9) controls a moving stage (3) to move at a constant velocity in a constant-velocity moving direction, and move over a predetermined distance in a predetermined-distance moving direction after a to-be-annealed object (2) is irradiated with the light beam on a range from one end thereof to the other end in the constant-velocity moving direction, thereby irradiating the whole surface of the to-be-irradiated object (2) with a uniform energy.
