In this electromagnet device, one opposing magnetic pole part 7a of the U-shaped member 6 of the electromagnet block 1 is notched, and a magnetic piece 10a of the permanent magnet block 2 is cut out.
Since the contact area between the opposite magnetic pole part 7b and the magnetic piece 10b of the permanent magnet block 2 is smaller than the contact area between the magnetic piece 10b of the permanent magnet block 2, the magnetic piece 1 in the magnetic circuit B
The magnetic resistance from the part sandwiching the permanent magnet 0a to the opposing magnetic pole part 7a of the electromagnetic block 1 is the same as that from the part sandwiching the permanent magnet of the magnetic piece 10b of the magnetic circuit A to the opposing magnetic pole part 7b of the electromagnetic block 1. It is larger than the magnetic resistance of . Since the magnetic resistances of the magnetic circuits A and B are equal in the other parts, the magnetic resistance of the magnetic circuit B is larger than that of the magnetic circuit A. As a result, when it is de-energized, the permanent magnet block 2
is always stable in a state where the magnetic resistance of the magnetic circuit is small. That is, when the excitation of the coil 4 is cut off from the state where the permanent magnet block 2 is attracted to the facing magnetic pole portion 7a side of the electromagnetic block 1, the permanent magnet block 2
moves toward the opposing magnetic pole portion 7b of the electromagnetic block 1, resulting in the state shown in FIG.

In the electromagnet device according to this invention, since at least one side of the coil is covered with a yoke that is thicker than the iron core, leakage magnetic flux can be reduced. Further, since the end portion of the yoke is formed to be thin, it is possible to reduce the thickness of the yoke. Furthermore, since the single stable structure is created by creating a difference in the magnetic resistance of the magnetic circuit that is formed when the coil is de-energized in both states in which the permanent magnet block or electromagnetic block moves forward and backward, Unlike stable electromagnet devices, there is no need to excite a coil to interfere with the magnetic flux of a permanent magnet, making it possible to realize a single stable electromagnet device with high magnetic efficiency.

(3) Utility model registration claim No. 1 in which the difference in magnetic resistance is achieved by providing a notch in one end of the magnetic material of the permanent magnet block that sandwiches the yoke end of the electromagnetic block. 1
Electromagnetic device as described in section. (4) Creating a difference in magnetic resistance is achieved by making one magnetic piece of the permanent magnet block thicker so that when the permanent magnet block or electromagnetic block moves forward or backward, the thinner side of the magnetic piece becomes thicker. 2. The electromagnet device according to claim 1, wherein the electromagnet device is constructed by not touching the opposing magnetic pole portion of the U-shaped member facing the U-shaped member.
