带电粒子在匀强磁场中的运动是每年高考的必考内容,最近几年,全国多个地方卷都出现了考查的带电粒子在圆形磁场中的运动,研究带电粒子在圆形磁场中的运动的特点,掌握分析此类问题的方法,对高考的复习备考有很大的现实意义。带电粒子在圆形磁场中的运动分为两种情景:一种是带电粒子沿半径方向射入圆形磁场,一种是带电粒子不沿半径方向射入圆形磁场。
The movement of charged particles in a uniform magnetic field is the compulsory part of the annual college entrance examination. In recent years, the movement of charged particles in a circular magnetic field has appeared in many local volumes around the country. The study of charged particles in a circular magnetic field The characteristics of sports, mastering the methods of analyzing such problems have great practical significance for the examination preparation of college entrance examination. The movement of charged particles in a circular magnetic field is divided into two scenarios: one is that the charged particles enter the circular magnetic field in the radial direction, and the other is that the charged particles do not enter the circular magnetic field in the radial direction.
