带电粒子在磁场中的运动是高中物理教学的重点内容,也是现今高考考查的重点。很多学生不能将这部分知识灵活应用于磁场分析,也不能建立粒子在磁场中运动的物理模型,磁场内容外延知识同学生物理概念理解间存在一定的偏差,学生存在一定的学习困难。对此,教师要能够把握重点,做好教学设计。一、带电粒子内容讲解1.注重细节,建立模型带电粒子在磁场中运动受到磁场力作用,由于速 The movement of charged particles in the magnetic field is the key content of high school physics teaching, which is also the focus of current college entrance examination. Many students can not apply this part of knowledge flexibly to the analysis of the magnetic field and can not establish the physical model of particles moving in the magnetic field. There is a certain deviation between the knowledge of the magnetic field content and the students’ understanding of the physical concept, and the students have some learning difficulties. In this regard, teachers should be able to grasp the key, good teaching design. First, the charged particles to explain 1. Attention to detail, the establishment of model Charged particles in the magnetic field by the magnetic field force, due to speed
