Magnetic equipment for use with magnetic circuits using high energy permanent magnet materials

Capabilities of magnetics equipment including Gaussmeters, fluxmeters, magnetizers, treaters and demagnetizers have changed significantly and will continue to change rapidly during the 1990s. The capability improvements demanded by permanent magnet users are being driven by a number of factors including: improved permanent magnet materials including sintered and bonded neodymium-iron-boron, samarium cobalt, and higher energy ceramics; new products using these improved magnet materials; total quality management (TQM)/ISO 9000; just in time manufacturing (JIT); and productivity improvement goals. These factors have combined to necessitate significant improvements in the capabilities of all types of magnetic equipment. This paper illustrates improvements that have been made in magnetics equipment and gives indications of the direction of improvements that will be available in the future
