METHOD FOR REVERSAL MAGNETIZATION OF MULTIPOLE PERMANENT MAGNETS AND MAGNETIC SYSTEMS

摘要

FIELD: magnetizing multipole magnets and magnetic systems. SUBSTANCE: method includes pre-magnetization of magnet or magnetic system to technical saturation in axial direction in double-pole electromagnet. Then its magnetization is reversed in electromagnet incorporating desired quantity of reversing zones. In the process strength of field built up by inductor poles in zones where direction of magnetizing field is same as direction of premagnetization equals 1.2 1.4 of magnet material coercive force. In opposing-direction zones magnetizing field strength should be sufficient for technical saturation of magnet material. EFFECT: improved saturation uniformity of poles; reduced width of neutral zones in axial reversing multipole magnets and magnetic systems. 1 cl, 3 dwg, 3 tbl
