On Earth, heat from the solid inner core drives complex fluid dynamics through convection in the planet's molten outer core, causing an electrical charge which generates a global magnetic field.

在地球上，从坚固的内磁芯的热量通过与炽热的外磁芯核的对流而形成流体动力，引起了电荷，进而由电荷产生了全球的电磁场。

Mercury is the only inner planet besides Earth with global magnetic field.

Another new discovery concerns Mercury's magnetic field. The planet, along with Earth, is alone among the terrestrial planets in having a global magnetic field.

另一个新发现是关于水星磁场的：水星和地球是所有的类地行星中有球星磁场的行星。

Lunar dynamo Scientists may have solved one of the Moon's enduring mysteries: why there are magnetised rocks on the lunar surface, when the Moon has no global magnetic field.

科学家可能已解开了一个存在多时关于月亮的谜团：为什么月亮没有全球性的磁场，而月球的表面还会有磁石的存在。

The satellite also found local magnetic fields, indicating that Mars once had a global magnetic field like earth 's, shielding it from cosmic rays.

这个卫星还发现了局部的磁场，表明火星曾经有一个全球的磁场正如地球上的那样，从而阻挡宇宙射线。
