摘要
对梯度磁场下2个相互作用的电子的运动方程进行了理论推导,利用C语言程序对该运动方程组进行数值求解,通过观察双电子及其质心的运动轨迹图像,得出了两电子及其质心在梯度磁场中的长时间平均位移均沿着零磁感线的结论.此外,在经典理论下,研究了在梯度磁场与沿零磁感线方向的匀强电场的共同作用下,两个相互作用的电子的运动轨迹,其结果是电子并不一定沿零磁感线运动,甚至可能出现明显的偏离.
Numerical analysis of trajectory of two interactive electrons in gradient magnetic field without electric field was presented. Numerical solution with C programming language showed that the average displacement of center of mass varied along curve where B=-0. Trajectory of two electrons in magnetic field and uniform electric field parallel to curve where B= 0 was also analyzed, which showed that electrons did not necessarily move along curve of B=0.
