There's a small solenoid under there that will push the domino up every minute.

下面有个小螺线管，每分钟都会把多米诺骨牌推上去。

Searching for those differences is one of the tasks for the people at the Compact Muon Solenoid, or CMS.

寻找这些差异是紧凑介子螺线管(CMS)工作人员的任务之。

And he built a calculator out of solenoids, and they acted as switches.

他用螺线管制作了个计算器，它们充当开关。

An ideal solenoid is a very common tool for creating a uniform magnetic field.

理想螺线管是种非常常见的生成场的工具。

An ideal solenoid has a length which is much, much larger than its diameter.

个理想螺线管的长度其直径。

See, that coil of wire is a special shape called a solenoid.

你看，那圈电线是个特殊的形状 它被称为螺线管。

The cross section of a solenoid looks like this.

螺线管的横截面看起来是这样的。

In the U.S., General Atomics has been able for example to deliver the first set of the central solenoid, ” said Bigot.

在美国，通用原子航空系统公司已经能够交付第批中央螺线管。”

We also talked about the forces between two parallel wires, and the magnetic field created by a solenoid.

我们还讨论了两条平行线之间的力，以及螺线管产生的场。

But, how does that work with all of those currents along the top of the solenoid?

但是，当螺线管顶部有所有那些电流时，这又是如何工作的呢？

Clockwise above the bottom row of currents in the solenoid means the magnetic field there is to the right.

在螺线管底部电流行之上，顺时针方向意味着那里的场向右。

On the top of the solenoid, the cross-section shows that all the currents are out of the screen and are in blue.

在螺线管的顶部，截面显示所有电流都垂直穿出屏幕，表示为蓝色。

This torus has a set of toroidal electromagnetic coils wrapped around it, paired poloidal coils above and below it, and a solenoid running through the middle.

这个环形结构有组环形电线圈缠绕在其周围，上下方配有组极向线圈，并且中间还贯穿有个螺线管。

And when a solenoid has a current running through it, it produces a magnetic field, basically all of which goes through the inside of the coils.

当螺线管有电流流过它时，它会产生个场，基本上它会在线圈内部通过。

And all the currents in the wires along the bottom of the solenoid to be in the same direction, in this case they are into the screen.

并且沿着螺线管底部的所有电流方向相同，在这种情况下它们是垂直进入屏幕的。

But, uh … Side 3 is completely outside the solenoid, and we now know that the magnetic field outside a solenoid equals zero.

但是， 呃… … 第三侧完全在螺线管之外，我们现在知道螺线管外部的场等零。

An ideal solenoid has zero magnetic field outside its cylinder.

理想螺线管在其圆柱体外具有零场。

Uh, you said this is an ideal solenoid where the length of the solenoid is much, much larger than the diameter of the solenoid, correct mr.p?

呃， 你说这是个理想螺线管，其中螺线管的长度其直径，对吧， 帕先生？

And clockwise below the bottom row of currents in the solenoid means the magnetic field there is to the left.

并且在螺线管底部电流行下方，顺时针方向意味着那里的场向左。

I can see how this is an ideal representation of solenoids.

我可以理解这是组理想化的螺线管表示。
