PURPOSE: To attempt to save energy consumed by an electromagnet device by eliminating its noise and holding its apparent power and power consumption while in operation to the minimum through such an arrangement wherein an AC power source is impressed on a series circuit, and No.1 and No.2 fixed iron cores are magnetically insulated from each other, but they are mechanically interconnected, and No.1 and No.2 movable iron core are also magnetically insulated from each other, but they are also mechanically interconnected.

CONSTITUTION: A fixed iron core 1a is wrapped around by a coil 2a, and a movable iron core 3a is arranged opposingly to the fixed iron core 1a. The yoke 16a of the fixed iron core 1a is magnetically insulated by a gap or a nonmagnetic body 14 and it makes a pair with a yoke 16b of another fixed iron core 1b, and under this condition, the fixed iron cores 1a and 1b are mechanically interconnected securely by rivets, etc. while they are magnetically insulated from each other. On the one hand, a movable iron core 3b is arranged opposingly to the fixed iron core 1b, this movable iron core 3b is magnetically insulated from the movable iron core 3a by a gap or a nonmagnetic body 15, and the movable iron cores 3a and 3b are mechanically interconnected securely by rivets, etc. while they are magnetically insulated from each other.
