带电粒子的运动在现行中学物理教材中有:在电场中的运动、在磁场中的运动以及在电场和磁场共存区域中的运动三种情形,它属于高考命题的热点之一,在历年高考中均有出现。本文结合高考物理题对带电粒子运动的特点、注意事项以及解答这类问题的基本思路作简明的分析。
The motion of charged particles in current middle school physics textbooks includes three situations: the movement in the electric field, the movement in the magnetic field, and the movement in the coexistence area of the electric field and the magnetic field. It belongs to one of the hot spots of the college entrance examination proposition, and has been in the college entrance examination over the years. Both appear. In this paper, a brief analysis of the characteristics of the charged particle motion, the precautionary points, and the basic ideas for answering such questions is given in conjunction with the college entrance examination physics questions.
