Claims

[Scope of utility model registration request]

Two permanent magnets arranged so that magnetic poles of the same polarity face each other with a predetermined distance apart, and a coil formed of a conductive wire and arranged between the opposing magnetic poles of the two permanent magnets, A coil arranged so that magnetic poles generated at both ends when current is applied face the magnetic poles of the two permanent magnets, and a space surrounded by the coil, at least a part of which is made of a magnetic material. a case that surrounds the coil and the permanent magnet and fixes the coil and the permanent magnet in their respective positions; and a device that supplies current to the coil, and an energizing device that can arbitrarily switch the direction of energization, and by using the energizing device to supply a current in a direction such that the magnetic poles generated at both ends of the coil have the polarity as required. An electromagnetic actuating device, characterized in that the moving member is moved in a predetermined direction by changing the magnetic flux distribution between the two permanent magnets and the coil.
