弹簧摆在匀强磁场中的运动分析

Motionanalysis of spring pendulum in uniform magnetic field

针对带有电荷的弹簧摆施加在竖直方向的匀强磁场的背景下,通过牛顿力学的方法得到了其运动学方程,从而发现其摆动平面在不停的进行旋转.同时按照初始条件的不同,将其在水平方向上的运动学方程化简为不同的曲线方程,进而得到了其运动的轨迹特征.

Aiming at the background of the charged spring pendulum exerting a uniform magnetic field in the vertical direction,its kinematic equation is obtained by the method of Newtonian mechanics,and it is found that its swing plane is constantly rotating.At the same time,according to the different initial conditions,the kinematic equations in the horizontal direction are simplified into different curve equations,and then the trajectory characteristics of its motion are obtained.
