Other objects become magnetic only when in a magnetic field caused by a permanent magnet or an electromagnet.

其它物体只有在处于永久磁铁或电磁铁形成的磁场中时才具有磁性。

And water would be all the more exciting on Ganymede because it is the largest moon in the solar system (larger even than the planets Mercury and Pluto) and, like earth, it has a permanent magnetic field that protects part of its surface from bombardment by certain sorts of life-destroying radiation.

Mr. Kohler is one of many 20-somethings who've cobbled together a few jobs to both pay the bills and gain more experience as they pursue a more permanent role in their field of choice.
