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.

指南针受地球磁力的控制。

Packing 45 Teslas of magnetic force.

拥有 45 特斯拉磁力。

We want to study this magnetic force

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，吸引着与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.

而且如果电磁力与强作用力的比值不是百分之一的话，生命就不会存在了。

Now another component of electromagnetism is magnetic forces.

电磁学的另一个组成部分是磁力。

Oh, we know the direction of the magnetic force.

哦，道磁力的方向。

It's the magnetic force that draws things together.

这是将事物聚拢的磁力。

I'm doing nature, electric force, magnetic force, math, I don't care about.

在研究自然、电力、磁力，数学嘛，不在乎。

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。

And it is also perpendicular between the magnetic force and the magnetic field.

并且磁力和磁场之间也相互垂直。

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。

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。

We have a greater force, or magnetic force.

有一个更大的力，或者说磁力。

Without a velocity, there is no magnetic force acting on this negative electric charge.

没有速度，就没有磁场对这个负电荷的作用力。

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

同样，您可以通过与磁力方向相反的方向移动磁铁来增加势能。

Orientation, though, is just one thing that affects magnetic forces.

然而，方向只是影响磁力的因素之一。

If it moves to 180 degrees what is our magnetic force at this point?

如果它移动到180度，那么在这一点的磁力是多少？

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。
