摘　　要：在球坐标系中,通过求解多个区域的拉普拉斯方程,得到匀角速转动带电薄圆盘产生的标量磁位和磁场分布,进而给出转动薄圆盘的中心、中心轴线上、近区和远区的磁场.By solving Laplace equation of several areas in spherical coordinates, w e get scalar magnetic poten-tial and magnetic field distribution that produced by a rotating charged body at constant angular speed. Then the magnetic strength of the rotating disc’s center,the rotating disc’s axis,the rotating disc’s far field and near region are obtained.

关 键 词：标量磁位 拉普拉斯方程 磁场分布
