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，电磁铁本身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， 你要使用是没有起重机电磁铁。

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电磁铁工作原种极端式。

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

中个是嵌入在静止部件中电磁铁，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，如果我让电荷通过这根导线，换句话说，如果我让电流通过这根导线， 并将缠绕在个通常不具磁性金属上， 它就会产生个磁场， 这样我们就创造出了所谓电磁铁。

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.

自然产生磁铁不足以举起巨大钢板，但用电线包裹铁芯并让电流通过， 瞧，你可以制造个可以举起汽车强大电磁铁。

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.

卡西欧兄弟决定用种称为“螺线管”设备来制造他们卡西欧计算器。因此，螺线管基本上是电磁体内部种金属柱塞，所以只是围绕它圈线圈。

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.

它不会与电磁辐射相互作用，也不会忽略电磁辐射，我们知道它并不重要，因为它包含称为重子粒子，我们可以通过反射光检测到它。

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磁铁是种特殊强力磁铁， 称为电磁铁，它们实际上可以用电打开和关闭。

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.

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

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.

当来自心脏电流通过两电磁铁之间细线时，细线会移动，移动投射阴影会被记录在移动感光纸上。

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.

由于等离子体粒子带电（电子带负电， 离子带正电），它们在高超音速飞行器上流动模式可以通过内部组电磁铁来改变。

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， 也就是秒钟后，会向电磁控制器发送个信号，告诉它改变电磁铁向。

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

所以你可以有像电磁铁和发电机这样东西，是因为电和磁是协同工作。

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

鼠标本质上只是个装有轮子磁铁，它跟随个由继电器开关位置控制电磁铁移动。

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

电磁体是在有电情况下变成磁铁材料。

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，您计算机将磁盘某些部分旋转经过磁头，磁头是个带有线圈小型电磁体。
