摘要
学生在学习安培力和洛伦兹力方向判定时掌握了左手定则,在判定电磁感应电流方向时又学习了右手定则,当出现综合性练习时,好多学生出现左手右手判定混乱的情况,为了解决这种判定混乱的情况,应该想个办法把左手定则和右手定则进行有效的统一。
The students grasp the left hand rule in the study of Ampere force and Lorenz force direction, in determining the current direction of electromagnetic induction and learn the right hand rule, when there are comprehensive exercises, many students have left hand to determine the chaotic situation, in order to solve this kind of judgement of chaos, should think of a way to effective unify the left and right hand rule.
