高中物理的电磁感应现象及规律是重要内容之一。对于电磁感应现象的产生,确定感应电动势的大小和感应电流的方向的一般规律——法拉第电磁感应定律和楞次定律,学生在学习时感到抽象,不易理解。为此,笔者设计制作了1套“电磁感应(系列)演示
High school physics electromagnetic induction phenomenon and the law is one of the important content. For the generation of electromagnetic induction phenomenon, to determine the general rules of the induced electromotive force and the direction of the induced current - Faraday’s law of electromagnetic induction and Lenz’s law, students feel abstracted when learning, not easy to understand. To this end, I designed a set of ”electromagnetic induction (series) demo
