摘　　要：阐述了产生感生电动势的本质和感生电动势的基本数学表达式,明确了产生感生电动势的基本条件,分析了在闭合导体和非闭合导体中产生感生电动势的典型例子,讨论了在非导体回路中不能形成感生电动势的根本原因。The paper illustrates the nature of induced EMF and then gives a mathematical expression for the induced EMF.The basic conditions for generating the induced EMF are clarified.As some typical examples,the induced EMF in closed circuits and open conductors is analyzed.Finally,the reason that there is no induced EMF in nonconductive circuits is discussed.

关 键 词：感生电动势 导体 感生电场力
