Researchers at the Institut des Sciences de la Terre (CNRS/Université Joseph Fourier Grenoble 1/IRD/Université de Savoie/IFSTTAR) have shown that turbulence, random motion that takes place in the molten metal in the Earth's core, makes a contribution to our planet's magnetic field. To obtain this result, they modeled the Earth's outer core using liquid sodium enclosed between two rotating concentric metal spheres, a set-up they dubbed the Derviche Tourneur Sodium (DTS) experiment1. Their findings have just been published in the journal Physical Review Letters.
