摘　　要：对传统自感演示实验的疑难问题作出理论分析,提出了新的实验教学设计.通过4个自制实验展示板,形成科学探究的逻辑链,依照引入自感概念→确立自感规律→解惑自感疑难→深化自感本质的教学逻辑逐步展开,弥补了传统自感演示实验的逻辑断裂.另外,将自感现象与力学现象类比,深化自感现象的本质——电磁惯性,实现新旧知识和力电思想方法的统一.According to the theoretical analysis of the difficult problems in the traditional self-inductance demonstration experiment,a new experimental teaching design was proposed.Through four demonstration circuits,the logic chain of scientific inquiry was formed.The teaching logic for introducing self-inductance concept,establishing self-inductance law,solving puzzles,deepening the nature of self-inductance was gradually developed,which made up for the logical break of traditional self-inductance demonstration experiment.In addition,by comparing self-induced phenomena with mechanical phenomena,the essence of self-inductance phenomena called electro-magnetic inertia was deepened,and the thinking methods of mechanics and electricity were unified.
