带电粒子在磁场中的运动问题是高中物理复习教学的重点、难点,也是历年高考的热点问题.要想在有限的考试时间内快速准确求解这类问题,需要有扎实的基础知识和较强的综合分析能力.此类题目综合性较强,解这类问题既要用到物理中的洛仑兹力、圆周运动的知识,又要用到数学中的平面几何及解析几何知识.如果能掌握带电粒子在磁场中运动情况的基本类型及相关问题的解法,就可成竹在胸、从容应试.下面对带电
The movement of charged particles in a magnetic field is a key and difficult point in high school physics review teaching. It is also a hot issue in the college entrance examination over the years. To quickly and accurately solve this type of problem within a limited examination time requires solid basic knowledge and strong Comprehensive analysis capabilities. These types of problems are more comprehensive. To solve such problems, we must use the knowledge of Lorentz force and circular motion in physics. We must also use plane geometry and analytical geometry knowledge in mathematics. The basic types of charged particle motion in a magnetic field and solutions to related problems can be tested on the chest and calmly. The following are charged.
