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。

They also suspect a fluid outer core generates the planet's magnetic field though convection.

他们还怀疑流体外核产生的磁场领域通过对流。

The interplay between the two leads to the formations of fluid outer core, basalt magmas, oceanic crust, and differential rotation between the inner core and mantle.

这两者之间的相互作用导致了流体外核的形成、玄武岩浆的产生、洋壳的形成、以及内核和地幔之间的差异旋转运动。

The research could help test simulations of how the outer, fluid core generates the Earth's magnetic field, which shields our planet and the teeming life on it from harmful cosmic rays.
