PURPOSE:To restrain the generation of heat in a magnetized substance, by installing the magnetized substance, laminating each sheet consisting of a tubular magnetic substance, in a magnetic circuit, and forming a closed circuit there electrically to an induced current. CONSTITUTION:A solenoid coil 1, a bobbin 2 and a yoke core 3 are all held in between, and the yoke core 3, a pole core 9 and a state core 11 are all installed in a magnetic circuit in the solenoid coil 1, constituting each magnetized substance. These magnetized substances are of each sheet consisting of a magnetic substance, and they come into a state of being opened inside an electric circuit so as not to form the loop continued internally themselves. Therefore, such a possibility that an eddy current might be produced inside the magnetized substance is preventable, thus generation of heat is restrainable. |
