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.

关键词: 标量磁位, 拉普拉斯方程, 磁场分布

Abstract: By solving Laplace equation of several areas in spherical coordinates,we get scalar magnetic potential 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.

Key words: scalar magnetic potential, Laplace equation, magnetic field distribution
