Abstract

PURPOSE:To increase the generating capability of a bicycle generator and to reduce the weight of the generator by alternately polarizing the outer periphery of the anisotropic circular-arc-shaped magnetic pieces formed in the radial parallel magnetic field, and then arranging fixedly the magnetic pieces along the outer surface of an annular core. CONSTITUTION:N-poles and S-poles are alternately polarized on the outer periphery of an anisotropic circular-arc-shaped ferrite magnet pieces 7 having radial anisotropy formed in a parallel magnet field, the magnetic pieces 7 are annular arranged along the outer periphery of a plurality of annular cores 6, and are integrally secured to the core 6, for example, with adhesive.
