Abstract
A magnetic circuit for a voice coil motor includes a yoke for guiding a magnetic flux, a permanent magnet magnetically detachably mounted upon the yoke for creating the magnetic flux, and a coil provided in correspondence to a magnetic gap formed by the yoke. The coil interlinks with the magnetic flux and is movable along the yoke. The yoke carries a projection, on a surface thereof on which the permanent magnet is mounted. The projection inhibits movement of the permanent magnet along the surface of the yoke. The permanent magnet is detachably mounted upon the surface of the yoke exclusively by a magnetic force associated with the magnetic flux of the permanent magnet.
