Claim:
1. A magnetic actuator, comprising: a movable unit, movable between a first position and a second position, the movable unit including an integrally formed eddy-current component and a first magnet yoke component; a second magnet yoke component to form a magnetic circuit with the first magnet yoke component; an electromagnetic coil to generate an exciting magnetic field when being energized, with magnetic lines generated by the electromagnetic coil being energized penetrating the magnetic circuit formed by the second magnet yoke component and the first magnet yoke component; an eddy-current coil arranged opposite to the eddy-current component and configured to enable an eddy current to be generated in the eddy-current component, so as to produce an electromagnetic repulsive force to the movable unit; and a permanent magnetic holding component to hold the movable unit in the first position or the second position.
