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析计算，绘制了该电机的场布图和化曲线簇。为该电机一步析、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，在原场方向测量化剩曲线，得到一系列化剩曲线。
