MAGNET ARRANGEMENT APPARATUS AND METHOD FOR CUTTING OFF THE OUTSIDE MAGNETIC FIELD IN DIRECT CURRENT GENERATOR

摘要

PURPOSE: A magnet array apparatus for magnetic shielding of a specified zone in the direct-current generator and a method thereof are provided to completely block the external magnetism by applying the magnetism offsetting method. CONSTITUTION: External magnetism is arranged along the periphery of a conducting wire(20). Magnets are arranged according to the periphery of the conducting wire. The arrangement induces the magnetic line of force to be opposed to the polarity. The magnetic line of force is generated in the external magnetism. The external magnetism is shielded on the conducting wire.
