The Earth itself has a magnetic force.

地球本身也有磁力。

A compass is ruled by the magnetic force of the Earth.

受地球磁力的控制。

Packing 45 Teslas of magnetic force.

拥有 45 特斯拉磁力。

We want to study this magnetic force

我们想研究下这个磁场。

Your thoughts are like a magnetic force that attracts similar thought patterns that are in harmony with your own.

你的思想就像一股磁力，吸引着你自己的思维模式相类似的思维模式。

And if the ratio of the electro magnetic force to the strong force wasn't one percent, life wouldn't exist.

而且如果电磁力强作用力的比不是百分之一的话，生命就不会存在了。

Magnetic force causes similar poles to repel one another, and opposite poles to attract.

磁力使相似的磁极相互排斥，相反的磁极相互吸引。

It creates a magnetic force field around us that deflects that solar wind up and away, making life down here much more enjoyable.

它在我们的周围构建了一个磁力场，抵挡并反射了那种太阳风，让这里的生活更快乐。

Again, you could increase the potential energy by moving the magnets opposite the direction of the magnetic force.

同样，您可以磁力方向相反的方向移动磁铁来增加势能。

This gives us more charged particles with magnetic fields in a small space, strengthening the magnetic force.

这让我们在狭小的空间内获得了更多带有磁场的带电粒子，从而增强了磁力。

Similarly, magnetic potential energy is the potential energy a magnetic object has due to the magnetic force from another magnet.

同样，磁势能是磁性物体由于另一个磁铁的磁力而具有的势能。

A combination of sunlight, dry heat, pressure and magnetic force is often used to alleviate pain from conditions such as rheumatoid arthritis and cervical spondylosis.

常结合阳光、干热、压力和磁力来缓解类风湿性关节炎和颈椎病等疾病的疼痛。

If you've handled two magnets, you felt magnetic forces, even when the magnets weren't touching each other.

如果您触摸两块磁铁，即使磁铁没有相互接触，您也会感受到磁力。

That's because magnetic forces are non-contact forces, which just means they can affect other objects they aren't even touching.

这是因为磁力是非接触力，这意味着它们可以影响它们甚至不接触的其他物体。

Magnets will attract or repel each other, and this attraction or repulsion is a magnetic force.

磁铁会相互吸引或排斥，这种吸引或排斥就是磁力。

But magnetic forces don't affect everything the same way.

但磁力不会以同样的方式影响一切。

In this video, we're going to talk about the magnetic forces between two magnets.

在本视频中，我们将讨论两个磁铁之间的磁力。

Plasma is scooped up by the magnetic force and is sent streaming out into space –  the starting point of the solar wind.

等离子体被磁力吸起并被送入太空——太阳风的起点。

So the direction of the magnetic force completely depends on the orientation of the magnets.

因此磁力的方向完全取决于磁铁的方向。

Gravitational, electric, and magnetic forces are all field forces, which means they act over distance and can affect a lot of objects.

引力、电力和磁力都是场力，这意味着它们作用于远距离并且可以影响许多物体。
