- the arrangement of the coil 1500 can be variously designed in addition to the ones illustrated. As the number of coils 1500 increases, the amount of current for switching between the magnetic field applied state and the non-applied state may be smaller, and the number of coils 1500 may be reduced. However, as the number of coils 1500 increases, the wiring becomes more complicated and the space occupancy can increase. Therefore, the number and arrangement of the coils 1500 should be optimized in a condition that can switch between the magnetic field applied state and the non-applied state, while being easy to control and minimizing the occupation of the internal space. This may be determined by an experiment in consideration of the number, strength, and thickness and length of the pole pieces 1110, 1120, 1200, 1300, and 1400 of the permanent magnet 1130.
