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

下面有一个小管，每分钟都会把多米诺骨牌推上去。

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

除非另有说明，此类中的所有管都将被视理想管。

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

你看，那一圈电是一个特殊的形状 它被称管。

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

组成的主要部件是他们仍在安装的超导磁体的管。

And I think car starter motors have got solenoids in them and so on.

我认汽车启马达内有电磁阀等等。

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

理想的管是创建均匀磁场的非常常见的工具。

The cross section of a solenoid looks like this.

管的横截面如下所示。

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

他用管制作了一个计算器，它们充当开关。

And then we have a solenoid that's connected to some double A batteries back there for power.

然后我们有一个电磁阀，它通过连接到后方的几节AA电池来获取电力。

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中央管。”

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之间的力，以及管产生的磁场。

Because when the cryogenic solenoid valve releases Fire will lose to ice everytime Dudes: ohhhhh with the fire threat neutralized.

因当低温电磁阀释放时， 火永远敌不过冰。伙计们：哦hhh， 火的威胁被消除了。

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

但是，管顶部的所有电流是如何工作的呢？

You know, standardized platform with the motors and the battery when it operates, little solenoids that will lock it in place and get low-voltage power.

还有带着发机和电池的标准平台，还有可以固定在一个地方收集低压电力的小丝管。

An ideal solenoid has zero magnetic field outside its cylinder.

理想的管在其圆筒外部具有零磁场。

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

管底部一排电流上方的顺时针方向表示磁场位于右侧。

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

在管的顶部，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.

我可以看出这是管的理想代表。

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

该磁场图是理想管产生的磁场的理想表示。

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

管中底部一排电流下方的顺时针方向意味着磁场位于左侧。
