如果电子随机地自转，各电子所产生的磁场会彼此抵消。

If the electrons are spinning at random, these fields cancel each other out.

当电流通过这样一根电线时，电流间的电子被迫调整其自转方向，以吻合电线上原有电子的自转方向。

When a current flows in such a wire, the electrons that flow as electricity are forced to align their spins to those of the local atoms embedded in the wire.

如果我们用一个，经典的比喻来考虑它的话，这经常会帮助我们建立起一些概念，就是我们可以把电子的， 自旋想象是它绕着轴自转。

One way to think about it, if we want to use a classical analogy, which often helps to give us an idea of what's going on, is the spin of an electron, we can picture it rotating on its own axis.
