自感系数定义辨析

Discriminating the Definitions of Self-Induction Coefficient

自感系数是电磁感应现象中的重要概念 ,关于它的定义可归纳为静态定义、动态定义和能量定义 .通过对这 3种定义的物理实质和适用范围的分析 。

Self-induction coefficient is an important conception in the electromagnetic induction.There are three definitions for it : static definition,dynamic definition and energy definition. This paper analyses in detail the physical essence and the range of applicatim of the definitions of self-induction coefficient. The energy definition is the stricter and more suitable definitoin formula of self-induction coefficient.
