Process and apparatus for magnetizing, on both sides, the surfaces of bodies to be magnetized

摘要

The process for magnetizing two opposite surfaces of a magnetizable body according to predetermined vectors includes the engagement of two magnetizing heads with each surface and rotation of the two heads relative to each other through a compensating angle corresponding to the angular deviation of actual magnetization from the desired position of magnetization vectors. Apparatus for performing such magnetization involves two juxtaposed magnetizing heads which are rotatable relative to one another.
