Except with light, the things doing the waving are electric and magnetic fields.

除开光，产生波动的是电场和磁场。

The speed this wave moves across space is determined by how well those wiggling electric and magnetic fields can create each other.

这种波在太空中移动的速度是由这些摆动的电场和磁场相互产生的能力决定的。

Maxwell's main achievement was encapsulating the behavior of electric and magnetic fields into a set of differential equations, now universally known as Maxwell's Equations.

麦克斯韦的主要成就是将电场和磁场的行为封装到一组微分方程中，现在普遍称为麦克斯韦方程组。

And using his laws today, we can see a pattern in the production of electric and magnetic fields.

今天使用他的定律，我们可以看到电场和磁场产生的模式。

We discussed electromagnetic waves and how changing electric and magnetic fields propagate through space.

我们讨论了电磁波以及电场和磁场如何在空间中变化。

But as the direction of current switches, the direction of both the electric and magnetic fields change.

但随着电流方向的改变，磁场和电场的方向也随之改变。

These oscillations are electromagnetic waves, and they're made up of changing electric and magnetic fields that travel through space.

这些振荡是电磁波，它们包括改变穿过空间的电场和磁场。

All of these fields tugging on each other essentially makes it harder for light's electric and magnetic fields to generate each other, compared to if they were in a vacuum with nothing in the way.

所有这些场相互拉扯，本质上使得光的电场和磁场更难相互产生，相比之下，如果它们处于真空中，是没有任何阻碍的。

Now, in order to calculate the energy carried by any electromagnetic wave, you need to know the magnitude of the electric and magnetic fields that compose that wave.

现在，为了计算任何电磁波携带的能量，您需要知道构成该波的电场和磁场的大小。

Albert Einstein praised Maxwell specifically for his contributions, but it was the combined effort of revolutionary minds like Maxwell, Faraday, and Gauss that we have to thank for our understanding of the interaction between electric and magnetic fields.

阿尔伯特·爱因斯坦特别赞扬了麦克斯韦的贡献，但正是麦克斯韦、法拉第和高斯等革命思想家的共同努力，我们应该感谢他们对电场和磁场相互作用的理解。
