He wrote his doctoral thesis on electromagnetism.

他写有关电磁学的博士论文。

Magnetism is one part of a dual force, electromagnetism.

电磁。

No force — not gravity or electromagnetism or anything — can cross it.

没有任何力量——重力、电磁或任何东西——能穿过它。

How electrons begin to move in the first place is a result of a force of nature called electromagnetism.

电子如何开始运动是一种被称为电磁力的自然力的结果。

Electrons are bound to an atom’s nucleus by electromagnetism.

电子通过电磁作用与原子核结合。

Electromagnetism also explains all of electricity.

电磁学也解释了所有电现象。

Quantum mechanics can describe electromagnetism and the strong and the weak force that works inside atoms, but it can't describe gravity.

量子力学可以描述电磁力和原子内部的强力和弱力，但不能描述引力。

Today we learned about Maxwell's equations and their unifying power in the field of electromagnetism.

今天我们了解了麦克斯韦方程组及其在电磁学领域的统一力量。

Dark matter is stuff that interacts with gravity but not electromagnetism, so can be felt, but not seen.

暗物质是与引力相互作用但不与电磁相互作用的物质，因此可以感觉到，但看不到。

But he put them together, to create a new, complete understanding of electromagnetism.

但他将它们放在一起，创造了对电磁学的全新理解。
