We also talked about transformers, and how they use mutual inductance to change voltage.

我们还谈到了变压，以及 它们如何使用互感来改变压。

Mutual inductance is also used in lots of other things, too – like wireless chargers, for example.

互感也用于许多其他方面——例如无线充。

Finally, we described how mutual inductance is used in wireless chargers.

最后，我们描述了如何 在无线充使用互感。

All those voltage changes are made using transformers, which take advantage of something called mutual inductance, where a change in the current in one coil leads to a change in emf in another, nearby coil.

所有这些压变化都是使用变压进行的，变压利用了一种称为互感的东西，其一个线圈的流变化会导致附近另一个线圈的动势发生变化。
