ABSTRACT:
At least one pair of adjacent magnets, magnet A of which serves both as an assistant magnet and a main magnet for a necessary magnetic pole is arranged so that it may have a magnetic component in the right angle direction with respect to the magnetized direction of another magnet B. Magnet A itself forms not only the main magnetic pole, but also is adapted to increase the flux density of magnet B in the outer circumference direction.
