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.

关键词: 静磁场, 轴对称, 矢势, 柱坐标系

Abstract: 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.

Key words: magnetostatic field, axial symmetry, vector potential, system of cylindrical coordinates
