楞次定律适用于磁通量的变化而产生电流的方向的判断,正确理解定律的含义是应用的关键,怎样正确理解这一定律呢?笔者认为从以下几点入手:一、从原磁场与感应电流的磁场的方向角度,理解为“增反减同”定律中的阻碍不是相反,原磁场的磁通量增大时,两磁 Lenz’s law applies to the magnetic flux changes in the direction of the current to determine the correct understanding of the meaning of the law is the key to the application, how to correctly understand this law? The author believes that the following points: First, from the original magnetic field and induced current Of the direction of the magnetic field angle, understood as “increase minus minus the same ” law of obstruction is not the opposite, the magnetic field of the original magnetic flux increases, the two magnetic
