At the other end, the current energizes an electromagnet and this attracts the armature.

在另一端，流使磁铁充，并吸到枢。

The Large Hadron Collider at Cern is a 27km loop of powerful electromagnets.

欧洲核子研究组织的大型强子对撞机是一个长达27公里的强大磁线圈。

This, though, required both high pressure, which is expensive to create, and the electromagnets themselves, which are costly to buy and costly to run.

不过这需要两种高压，成本很高，磁铁本身的购买和运行成本就很高。

For you though, you're going to use the electromagnet without the crane.

不过对你来说， 你要使用的是没有起重机的磁铁。

These electromagnets will help keep the superhot plasma in the center of a tube.

这些磁铁有助于超热等离子体保持在管子的中心。

And this machine is just an extreme way that we can demonstrate how electromagnets work.

而这台机器只是我们展示磁铁工作原理的一种极端式。

One is an electromagnet embedded in a static component, known as a stator.

其中一个是嵌入在静止部件中的磁铁，这个静止部件被称为定子。

So if I run charges through this wire, in other words if I run current through this wire and I wrap it around a metal which is not normally magnetic it will generate a magnetic field and we have created something called an electromagnet.

所以，如果我让过这根导线，换句话说，如果我让流过这根导线， 并其缠绕在一个常不具磁性的金属上， 它就会产生一个磁场， 这样我们就创造出了所谓的磁铁。

Naturally occurring magnets aren't powerful enough to lift up huge slabs of steel, but wrap an iron core with wires and run a current through and voila, you can create a powerful electromagnet that can lift cars.

自然产生的磁铁不足以举起巨大的钢板，但用线包裹铁芯并让流过， 瞧，你可以制造一个可以举起汽车的强大磁铁。

The Casio brothers decided to build their Casio calculators off a device called a " solenoid." So, a solenoid is basically a metal sort of plunger inside an electromagnet, so just a coil of wire that runs round it.

卡西欧兄弟决定用一种称为“螺线管”的设备来制造他们的卡西欧计算器。因此，螺线管基本上是磁体内部的一种金属柱塞，所以只是围绕它的一圈线圈。

It doesn't interact with or omit electromagnet radiation and we know that it can't be matter as if it was it would contain particles called baryons which we'd be able to detect it through reflected light.

它不会与磁辐射相互作用，也不会忽略磁辐射，我们知道它并不重要，因为它包含称为重子的粒子，我们可以过反射光检测到它。

Magnets like the kind use in Maglev trains and the ones used in junkyards are a special kind of powerful magnet called an electromagnet, they're magnets that can actually be turned on and off using electricity.

磁悬浮列车和垃圾场中使用的磁铁是一种特殊的强力磁铁， 称为磁铁，它们实际上可以用打开和关闭。

General Fusion, too, relies on sophisticated software to control the pistons and so shape the plasma appropriately. But Dr Laberge believes that doing without electromagnets has simplified the design and removed potential points of failure.

用融合也依赖复杂的软件来控制活塞，从而适当塑造等离子体。但拉贝热博士认为，不使用磁铁简化了设计，并消除了潜在的故障点。

When electrical current from the heart passed through a fine wire or string, set between two electromagnets, the string moved, and the shadow cast by its movements was recorded on moving photographic paper.

当来自心脏的流过两磁铁之间的细线时，细线会移动，其移动投射的阴影会被记录在移动的感光纸上。

Since a plasma's particles are electrically charged (the electrons negatively and the ions positively), their flow pattern over a hypersonic vehicle could be altered using a set of electromagnets within.

由于等离子体的粒子带（子带负， 离子带正），它们在高超音速飞行器上的流动模式可以过内部的一组磁铁来改变。

And after 32,768 cycles, which takes one second, a signal is sent to the electromagnetic controller, telling it to flip the direction of the electromagnet.

并且经过32,768个周期， 也就是一秒钟后，会向磁控制器发送一个信号，告诉它改变磁铁的向。

So the reason that you can have things like electromagnets and dynamos is because electricity and magnetism kind of work together.

所以你可以有像磁铁和发机这样的东西，是因为和磁是协同工作的。

The mouse was just a magnet on wheels essentially, following an electromagnet controlled by the position of the relay switches.

鼠标本质上只是一个装有轮子的磁铁，它跟随一个由继器开关位置控制的磁铁移动。

Electromagnets are materials that become magnets in the presence of electricity.

磁体是在有的情况下变成磁铁的材料。

To read that information, your computer rotates sections of the disk past the head, which is a small electromagnet that has a coil of wire.

要读取该信息，您的计算机磁盘的某些部分旋转经过磁头，磁头是一个带有线圈的小型磁体。
