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磁体来实现他这种把戏。

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

铈也用于永磁体，显然在磁学领域有明显应用。

A larger ring, called a rotor, contains permanent magnets and rotates around the stator.

一个较大环，称为转子，内含永磁体，并围绕定子转。

Every second, the electromagnet switches directions, thus causing the magnet inside the driver gear to rotate 180 degrees in order to align its permanent magnet with the fields produced by the electromagnet.

每秒钟， 磁铁改变方向，从而使得驱动齿轮内磁铁转180度， 以便将其永磁体与磁铁产生磁场对齐。

They are used in super permanent magnets and therefore on that absolutely critical instrument of economic warfare, which is called the vacuum cleaner.

它们被用于超强永磁体， 因此成为经战中一个绝对关键工具，也就是吸尘器。

As we increase the magnetic field it quickly, all of these dipoles align, the domains align and we have a permanent magnet.

当我们迅速增强磁场时，所有磁矩都会对齐， 磁畴也会对齐， 从而形成永磁体。

The pump is a brushless DC motor, constructed from a PCB, a control chip, and a stator on the dry side, a barrier in the middle, and then the permanent magnet rotor and impeller on the liquid side.

泵是一款无刷直流机，由干侧路板、控制芯片和定子，中间隔板， 以及液侧永磁转子和叶轮组成。

Well in a permanent magnet or in an induced magnet, what we are doing is lining up those dipoles and now the whole object has a dipole as well, a north and a south.

在永磁体或感应磁体中，我们所做就是使这些偶极子对齐， 这样一来整个物体也有了一个偶极子，也就是有了南北两极。

Permanent magnets do not need a power source, but this means that we can also turn electromagnets on and off, which is pretty cool when you think about it.

永磁体不需要源，但这意味着我们也可以打开和关闭磁体，想想看，这真是太酷了。

On the other hand, permanent magnets are always on.

另一方面，永磁体始终处于开启状态。

And so if I were to change this and make it a permanent magnet, watch what happens to those domains.

所以如果我把这个变成永磁体，看看这些磁畴会发生什么变化。

Do we have a permanent electrostatic magnet?

我们有永久静磁铁吗？

This is different from a permanent magnet because permanent magnets don't need this wire.

这与永磁体不同，因为永磁体不需要这种线。

And it will make a permanent magnet.

并且它会成为一个永磁体。

So let's take a look at that and compare permanent magnets to electromagnets.

让我们看一下并将永磁体与磁体进行比较。

If you heat up a permanent magnet above what is called the curie temperature, all those magnetic fields get scrambled and it is not a magnet anymore.

如果你将永磁体加热到所谓居里温度以上，所有磁场就会变得混乱， 它就不再是磁铁了。

And so what is a permanent magnet?

什么是永磁体？

Permanent magnets also have fixed poles.

永磁体也有固定磁极。

This makes electromagnets quite different from permanent magnets.

这使得磁体与永磁体有很大不同。

So now what you have created is a permanent magnet.

所以你现在创造是一个永磁体。
