| 摘 要： | 求匀角速转动带电体的磁场是一类典型的静磁场边值问题．传统的解法是用磁矢势结合边界条件解泊松方程，其过程复杂，计算冗长．根据（连带）勒让德多项式的性质和加法公式，利用矢势叠加法导出了旋转带电圆盘的空间磁场分布，并对结果进行了讨论．

| Abstract: | Computation of the magnetic field produced by a rotating charged body is a classical magnetostatic boundary-value problem. The traditional solutions is to solve Poisson＇s equation with the help of magnetic vector potential and the boundary conditions. But the process is complicated. According to character and additive formula of Legendre polynomial, the space magnetostatic field of a rotating charged disc is calculated by superposition method of vector potential. |

| Keywords: | vector potential Legendre polynomial axial symmetry superposition principle |
