摘要
楞次定律是电磁感应过程中判断感应电流方向的定律。不论它以何种方式表述,表面上都有一个共同点,就是感应电流的磁场与原磁体磁场之间的相互阻碍关系,而实际上这种阻碍关系正是能量的转化和守恒定律在电磁感应现象中的具体体现。
Lenz＇s Law is the law used to determine the direction of the inductive current during the electromagnetic induction.However the law is expressed,it comes out into open to a joint -the interobstruction between the inductive magnetic field and the original magnetic filed,which ,in fact,embodies the law of energy conversion.
