洛伦兹力与安培力的关系,是中学物理教学中的难点,现对此问题进行讨论。一、洛伦兹力对电荷是否做功分析1:如图1所示的电路中,设导体在外力的作用下以速度v1向右匀速运动时,导体内的正电荷q随导体向右匀速运动的同时,以速度v2沿导体匀速运动,此时电荷的合 The relationship between Lorentz force and Ampere force is a difficult point in the teaching of physics in middle schools. Now, the issue is discussed. 1, Lorentz force on the charge whether to do the work analysis 1: As shown in Figure 1, the conductor set in the force under the action of the speed v1 to the right uniform motion, the positive charge in the conductor q with conductor to the right uniform motion At the same time, the speed of v2 along the conductor uniform motion, at this time the combined charge
