N the principle that the direction of the current induced in a circuit by a changing magnetic field is such that the magnetic field produced by this current will oppose the original field 楞次定律 [physics]
How many of you know Lenz's law?
你们又多少人知道楞次定律？
So Lenz's law says it's going to do whatever it can so that it retains no field inside.
所以楞次定律说它会尽可能地，保持内部没有磁场。
Lenz's law states that the induced current flows in a direction such that it opposes the change producing it.
楞次定律指出感生电流所流动的方向，是要对抗产生的电流改变。
