The physics at play is the Lorentz Law.

这其中涉及的物理学原理是定律。

A lorentz invariant or field theory approach.

不变量和场论步骤。

It's also  interesting to note that the physics of magnetic fields deflecting moving electrons, called the  Lorentz Force, is the driving principle behind all electric motors, just with coils of wires  and different configurations of magnetic fields.

同样有趣的是， 磁场偏转移动电的物理原理，称力， 是所有电动机背后的驱动原理，只需线圈和不同置的磁场即可。

This relationship can be quantified with something called the Lorentz factor, which is defined by this equation.

这种关系可以用来量化，这是的定义公式。

At 86.6% of the speed of light, the Lorentz factor is 2, meaning time will pass twice as slowly aboard the spaceship.

当速度光速的 86.6％ 时， 2，意味着飞船上的时间慢原来时间的一半。

Of course, Einstein didn't figure out this special principle of relativity in 1905 - it was already done by a guy named Lorentz ten years earlier.

当然，在1905年，爱斯坦并没有想出这种特殊相对性原则早在10年前就发现了它。

A basic law of physics called the Lorentz force  is that all moving charged particles such as electrons are affected by magnetic fields.

物理学的基本定律称力，即所有运动的带电粒（例如电）都会受到磁场的影响。

However, if the electron were traveling perfectly down the center along the optical axis, it wouldn't experience any Lorentz force from the magnetic fields and would just continue down the center.

然而， 如果电沿着光轴完美地沿着中心移动，它不会受到来自磁场的任何力， 而只会继续沿着中心向下移动。

In fact, the problem with relativity wasn't that it involved a lot of differential equations, Lorentz transformations, and other complicated mathematics (though it did-even Einstein needed help with some of it), but that it was just so thoroughly nonintuitive.

实际上，相对论的问题并不在于它涉及许多微分方程、变换和其他复杂的数学（虽然它确实涉及——有的方面连爱斯坦也需要别人帮忙），而是在于它不是凭直觉所能完全搞懂的。
