ABSTRACT:
A magnetic actuator includes a housing; a first permanent magnet and a second permanent magnet placed in the housing and being relatively rotatable in a plane including a magnetization direction; a magnetic-field generating unit outside of the housing, the magnetic-field generating unit generating a magnetic field that relatively rotates the first permanent magnet and/or the second permanent magnet in a direction such that the first permanent magnet and the second permanent magnet generate a repulsive force against each other; and a first guiding portion provided in the housing to regulate a direction in which the first permanent magnet and the second permanent magnet relatively move by the generated repulsive force.
