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

我还谈到了变器，以及 它如何使用互感来改变。

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

最后，我描述了如何 在无器中使用互感。

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

互感也被用于许多其他方面——例如无器。

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.

所有这些变化都是使用变器进行的，变器利用了一种称为互感的东西，其中一个圈中的流变化会导致附近另一个圈的动势发生变化。
