带电粒子在磁场中运动的解题技巧

Problem-solving skills for moving charged particles in a magnetic field

磁场一直是高考物理考察的重点,同时也是学生的难点,为了能够让学生更好地掌握知识和技能,提出了一种带电粒子在磁场中运动的解题技巧,这种技巧同时也适用于解析复合场中粒子的运动问题.

Magnetic field has always been the focus of the physical examination of college entrance examinations, and it is also a difficult point for students. In order to enable students to better grasp the knowledge and skills,a problem-solving technique for moving charged particles in a magnetic field is proposed. This technique is also suitable for solving the motion problems of particles in a composite field.
