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分析计算，绘制了该电机分布图和化曲线簇。为该电机进一步分析、改良提供了重要依据。

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

将该半球左半部分分成18个5o瓣，按5o间隔逆时针转动，在原方向测量化剩曲线，得到一系列化剩曲线。
