magnetization

It was analyzed and calculated through final element analysis (FEA) and the profiles of tile magnetic field and corves of magnetization were plotted.

并通过有限元方法对其进行析计算，绘制了该电机的磁场布图和磁化曲线簇。为该电机进析、改良提供了重要的依据。

Angle this magnet withershins to an angle that is the multiple of 5o, then measure its magnetizing remanent magnetization curves along H direction.

将该半球的左半部成18个5o的瓣，按5o间隔逆时针转动，在原磁场方向测量磁化剩磁曲线，得到系列磁化剩磁曲线。
