Now --  -- So we now know that we are able to transfer enormous amount of currents inside superconductors, so we can use them to produce strong magnetic fields, such as needed in MRI machines, particle accelerators and so on.
现在---- 好的，现在我们都了解了 我们能够传输超导体内部的大量电流， 那么我们能够利用它们制造强大的磁场， 诸如在核磁共振成像仪，粒子加速器等机器中所需要的。
