“探究感应电流产生的条件”、“楞次定律”、“法拉第电磁感应定律”是“电磁感应”的核心内容.这三节均是以实验为基础而总结出规律的教学,所以实验是教学成功的关键因素.笔者根据教学需要“量身定制”了3套实验装置,谨以此文与大家分享.1“探究感应电流产生的条件”演示实验1.1原有实验不足 “Explore the conditions of induced current ”, “Lenz’s law ”, “Faraday’s law of electromagnetic induction ” is “electromagnetic induction ” the core content of these three sections are based on experiments and summed up the law Of the teaching, so the experiment is the key factor for the success of teaching.According to the teaching needs of the author “tailor ” 3 sets of experimental devices, would like to share with you this article. 1 “to explore the conditions of induced current ” demonstration experiment 1.1 The original lack of experiments
