摘要
根据毕奥—萨伐尔定律推导出圆环电流磁场分布的积分表示,利用MATLAB的符号积分给出计算结果,并绘制磁场分布的三维曲线。在数值结果中选取一些代表点讨论磁场的分布规律。
This paper derives the integral representation of the magnetic field distribution of circular current according to Biot - Savart Law, gives the computed results using the symbolic integration of MATLAB, and draws the three - dimensional curve of the magnetic field distribution. Some representative points in the computed results are selected to discuss the dis- tributed rule of the magnetic field.
