Extremely powerful storms distort the magnetic field even futher, inducing electric currents that span the continents.

极端强大的太阳风暴会扭曲整个地球磁场，甚至会进一步影响到全球的供电。

It turns out that magnetic fields do induce electric currents.

事实证明，磁场确实会 产生电流。

When Faraday discovered that magnetic fields induce electric currents, he got kind of lucky.

当法拉第发现磁场 感应电流时，他有点幸运。

That is, until two physicists, Joseph Henry and Michael Faraday, both on their own, figured out what was happening: It turns out that magnetic fields do induce electric currents.

也就是说，直到两位物理学家约瑟夫·亨利和迈克尔·法拉第独自弄清楚发生了什么：事实证明磁场确实会感应电流。
