Abstract
A magnetic circuit includes a multi-pole magnet mounted on a predetermined surface of a yoke and having magnetic poles formed in a direction perpendicular to the predetermined surface of the yoke. The multi-pole magnet is separated into two pieces, and a single-pole magnet is interposed between the two pieces of the multi-pole magnet. Magnetic poles of the single-pole magnet are formed in a direction different from the direction in which those of the multi-pole magnet are formed.
