楞次定律是高中物理教学中一个非常重要的规律,教材上是这样描述的“感应电流的磁场总要阻碍引起感应电流的磁通量的变化”。告诉我们一个判断感应电流方向的方法,是不是在什么情况下都能应用它来判定感应电流方向呢?
Lenz’s Law is a very important law in high school physics teaching. The teaching material is described in this way as “The magnetic field that induces current always hinders the change of magnetic flux that induces current”. Tell us how to determine the direction of the induced current. Is it possible to use it to determine the direction of the induced current?
