本文首先简单枚举了产生感应电流的5种外显的现象,然后结合运用简单枚举归纳法和消去归纳方法将条件总结为导体和磁场间的相对运动和电流的变化两大类条件,最后在全面综合归纳为磁通量变化这一本质条件。本文侧重在教学的过程中渗透归纳思维,注重物理科学方法的训练。 In this paper, we firstly enumerate five kinds of explicit phenomena that produce induced current, and then combine the conditions of simple enumeration induction and elimination induction to summarize the conditions of relative movement and current change between conductor and magnetic field. Finally, In a comprehensive synthesis of the flux of changes in the nature of this condition. This article focuses on the induction of thinking in the process of teaching, focusing on physical science methods of training.
