Magnetizing Fixture Provides 3-D Flux Flow

Magnetizing fixtures produce the fields required to coerce permanent magnets permanently. These fixtures come in different shapes and sizes determined by the associated permanent magnet. A recent fixture requirement called for magnetization of a high-energy-product magnet ring with eight asymmetric poles and alternating 30 and 60 spans. This fixture required an axial flux path as well as the normal X-Y path. The three dimensional flux flow would enable the fixture to produce a higher magnetizing force than previously possible.
