摘　　要：针对求解定轴匀速转动带电导体球周围的磁场分布提出一种新的计算方法;通过分析导体球上电荷的轨道运动情况进一步求解出空间各点的磁感应强度大小;同时利用Comsol软件模拟其全空间的磁感线分布;并将理论计算的结果与仿真结果相对比,两者数据基本吻合,验证了理论计算的准确性及仿真模拟的可行性和准确性.A new calculation method is proposed to solve the magnetic field distribution around a charged conductor ball rotating at a constant speed on a fixed axis.By analyzing the orbital motion of the charge on the conductor ball, the magnetic induction intensity of each point in space is further solved.At the same time, Comsol software is used to simulate the distribution of magnetic induction lines in the whole space, and the theoretical calculation results are compared with the simulation results.The data of the two data are basically consistent, which verifies the accuracy of theoretical calculation and the feasibility and accuracy of simulation.
