APPARATUS FOR GENERATING UNIFORM MAGNETIC FORCE

摘要

PURPOSE: An apparatus for generating uniform magnetic lines of force is provided to efficiently manufacture a magnetic reluctance element having high precision by applying a uniform magnetic field to a part of the working object. CONSTITUTION: An apparatus for generating uniform magnetic lines of force comprises a plurality of permanent magnets(20), a fixing ring(10), and a focusing ring(30). The permanent magnet is composed of a general permanent magnet. All permanent magnets have the same magnetic force. The fixing ring fixes the permanent magnet at a constant interval. The fixing ring has an enclosed flat type surrounding a predetermined region. The fixing ring is used to set each magnetic pole of a plurality of permanent magnets to be parallel along a horizontal direction of the region. The focusing ring is made of a magnetic material. The focusing ring is arranged to surround the outside of the fixing ring.
