By trapping these tiny pieces of floating plastic, the mucus acts like a magnet – an object that attracts certain materials, like metal, or in this case, microplastic waste.

通过吸附这些漂浮的塑料小颗粒，这种黏液就像体一样——这种物体能吸附某些材料，如金，在这种情况下是指微塑料废物。

挺复杂的，他跟激光和原子体打交道。

So when Dr Murdin placed the crystal in a 30-tesla magnet at Radboud University in the Netherlands (his lab in Guildford lacks the necessary kit), he was mimicking the conditions in a 100,000-tesla white dwarf.

因此，当穆迪博士这个晶体放一个30特斯拉的体（这个体在荷兰的内梅根大学）中时，因为他在格尔福德的实验室缺少必要的设备，他是在模仿一个100，000特斯拉场强度的白矮星所处环境。

In 2006, Suchitra Sebastian and Neil Harrison put a few flakes of Chinese purple into the magnet's core, and saw things never seen before.

在 2006 年，苏次塔·塞巴斯蒂安和尼尔·哈里斯将几块中国紫碎片放入体核心内，然了前所未见的情况。

One, the Earth is really just one big magnet, and second, it turns out the sun gives of a lot more than just light.

一，事实证明地球真的是一个巨大的体，二，事实证明太阳提供的东西不仅仅是光。

And with the exception of a compass or other magnetic object, we rarely see matter respond to a magnetic field.

除了指南针和其他体，我们很少物质受场的影响。

When unpaired electron spins line up parallel to each other, you get ferromagnetism, or a mineral that's an actual magnet.

当未配对的电子自旋互相平行时，你将见铁性，一个实际上是体的矿物。

Dr Vetrovec intends to perform his version of the trick at atmospheric pressure, and using permanent magnets.

维特威克博士想要在大气压力下使用永体来实现他的这种把戏。

The Earth has a molten iron core that rotates quickly, turning it into a giant magnet.

地球有一个快速旋转的熔融铁核，把地球变成了一个巨大的体。

The Leather Loop comes in a soft, quilted leather that conceals magnets for fastening and adjustment.

皮质回环形表带以柔软的裄缝皮革为材料，内藏体，便于收紧及调整。

Sometimes, a gem that's normally repelled by magnets will have bits of iron inside it, which will make it attracted to magnets instead.

有时，一个通常被体排斥的宝石如果含有少量铁元素，反而这会使得它被体吸引。

The magnetic field around the Earth is called the magnetosphere, and like a magnet, it has a north pole and a south pole.

围绕着地球的场被称为层，就像一个体拥有一个南极和一个北极。

A discovery made here at the national high magnetic field laboratory, home of the 45t hybrid, the world's most powerful magnet.

这项发现在国家高场实验室中做出 45-T 混合体，世界最强的铁就坐落于此。

So what draws scientists like, well, like a magnet to the 45t hybrid?

那是什么让科学家们像铁一样被 45-T 混合体所吸引呢？

On the other hand, a material with all its electrons paired up is slightly repelled by a magnetic field, because when the electrons move around in an atom, they make magnetic fields of their own, which repel other magnets.

另一方面，所有电子都配对的材料对场有轻微的排斥，因为当电子在原子内部运动时，它们自身产生了一个场，这个场排斥了其他体。

Inside the magnet, the molecules of Chinese purple became a single magnetic wave.

在体内，中国紫的分子变成了单一的波。

In fact, the same transition metals that give gems their color can make them drawn to magnets.

事实上，过渡金元素赋予了宝石颜色，同样使它们被体吸引。

Cerium is also used in permanent magnets for obvious applications in magnetism.

铈也用于永体，显然在学领域有明显应用。
