An attempt is made to explore self-induced EMF in theory by a quantitative means, and to demonstrate the corresponding contents or its experimental design by using the instruments such as voltage effect and digital oscillograph.

• 摘要用定量研究的方法，从理论上对影响自感电动势产生和测量的因素进行了探讨分析，同时用“电压效应”和数字示波器等仪器对相应内容进行了演示或验证性实验。
