Abstract
A method for the manufacture of an annular magnet, which comprises depositing, on the opposite sides of an annular material of magnetic substance, magnetizing members regularly spaced circumferentially in conformity with the shape of said annular material and opposed perpendicularly to each other across said annular material and forming magnetic fluxes through paired magnetizing members in alternately opposite directions thereby magnetizing said interposed annular material.
