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

下面有一个小螺线管，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)工作人员任务之一。

Unless otherwise stated, all solenoids in this class will be treated as ideal solenoids.

除非另有说明，所有螺线管都将被视为理想螺线管。

The cross section of a solenoid looks like this.

螺线管横截面如下所示。

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

用螺线管制作了一个计算器，它们充当开关。

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

理想螺线管是创建均匀磁场非工具。

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

你看，那一圈电线是一个特殊形状 它被称为螺线管。

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一批央螺线管。”

The main component of the composition was the solenoid of the superconducting magnet they were still installing.

组成主要部件是们仍在安装超导磁体螺线管。

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力，以及螺线管产生磁场。

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

但是，螺线管顶部所有电流是如何工作呢？

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

螺线管底部一排电流上方顺时针方向表示磁场位于右侧。

An ideal solenoid has zero magnetic field outside its cylinder.

理想螺线管在其圆筒外部具有零磁场。

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

在螺线管顶部，横截面显示所有电流均从屏幕流出并呈蓝色。

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

我可以看出这是螺线管理想代表。

This magnetic field map is an ideal representation of the magnetic fields caused by an ideal solenoid.

该磁场图是理想螺线管产生磁场理想表示。

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

螺线管底部一排电流下方顺时针方向意味着磁场位于左侧。

Now, we get to derive the equation for the magnetic field inside a solenoid!

现在，我们可以推导出螺线管内磁场方程！

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，它会产生一个磁场，基本上它会在线圈内部通过。

Again, this solenoid is made out of one wire, which means all of these currents are in the same wire and have the same magnitude.

同样， 该螺线管由一根导线制成，这意味着所有这些电流都在同一导线并且具有相同幅度。
