旋转非导体带电球面磁场的全空间解析解新探

A NEW METHOD OF FULL-SPACE ANALYSIS OF THE MAGNETIC FIELD FROM CHARGED ROTARY NON-CONDUCTIVE SPHERE

求旋转非导体带电球面的磁场是一个典型的静磁场边值问题．传统的解法之一是用磁标势概念，结合边界条件解拉普拉斯方程，其过程复杂，计算冗长．本文在介绍矢势 Ａ、磁化强度 Ｍ 和电场强度 Ｅ 三者关系的基础上，用类比的方法，巧妙简捷地给出了问题的全空间解析解。

Based on the formular A=ε 0μ 0ρM×E,full-space analysis of the magnetic field from charged rotary non-conductive sphere is obtained, by a way of analogy and discussions are made.\;
