本発明の１的は旨いエネルギー檀全Ｍする磁性材料金ｆ
辞る４ｉｆｆ場中圧粉成形方法ケ唾供することである。Previously, all electromagnets were used as magnets. When the magnetic material has a very good coercive force, such as rare earth colt, it is safe to increase the output of the electromagnet as the coercive force fj deteriorates. In order to supply a large tlj current, it is necessary to use a magnetic field il''j, which is usually 15, for practical purposes, rather than using a scale that has disadvantages such as increasing the size of the electromagnet and increasing the resistance of the coil. 0000e Culm m2, maximum 1 [,
5 is 20,0000 e, so it cannot be said to be sufficient to fully orient the rare earth magnetic phase family.
The 4iff is to provide an in-situ powder compaction method.
