摘要
洛伦兹力与安培力的关系,是中学物理教学的难点.洛伦兹力与安培力关系的争论中存在困惑,为什么洛伦兹力永不做功而其宏观表现的安培力常常可以做功？从“合力说”“碰撞传递”“霍尔电场”3种观点进行分析,分析了安培力产生的微观机理,深入探讨了两者的关系.
Purpose The relationship between Lorentz force and Ampere force is the difficulty of physics teaching in secondary schools. In the debate of Lorentz force and Ampere forces there is confusion., why Lorentz force never work and its macro performance Ampere force can often do work？ Method From the three perspectives, ＂The doctrine of cohesion＂, ＂Collision transfer＂ and ＂Hall electric field＂, the microscopic mechanism of Ampere force is analyzed, and the relationship between them is discussed in depth.
