摘要
对于轴对称的静磁场,推导出了矢势的柱函数展开式,得出了用对称轴上的磁场表示轴外任意点磁场分布的级数展开式.最后,给出了用这两种方法求解轴对称静磁场的例子.
To solve axially symmetrical magnetostatic field, the cylindrical function expansion of vector potential is derived, the series expansion for expressing off-axis magnetic field by the axial values is obtained.At last, some examples using the two methods are given.
