摘要
法拉第电磁感应定律描述了动磁与电的关系,是电磁学的基本定律之一,该定律也因此被麦克斯韦归入揭示宏观电磁现象及规律的麦克斯韦方程组。本文从电磁感应定律的表达式入手给出电感线圈的伏安关系式,并分别从电工及电子领域举例说明基于电磁感应定律的电感线圈的应用及带来的问题。
Faraday's electromagnetic inductive law describes the relationship between dynamic magnetism and electricity, it is one of the basic laws on electromagneties. So Maxwell incorporates it into Maxwell's equations, as description of macroscopic electromagnetic phenomenon and law. Firstly, electromagnetic induction law is stated, volt-ampere relation is given on inductance coil secondly, Application and problems based on electromagnetic in- ductive law about inductance coil is respectively illustrated from electroteehnics and electronics.
