It is thought that the energy necessary to heat the corona is provided by turbulent motion in the convection zone below the photosphere, and two main mechanisms have been proposed to explain coronal heating. (newworldencyclopedia.org)
It is generated by turbulent motions of liquid iron in Earth's core. (sciencedaily.com)
The data enabled the researchers to show that turbulent motion increases the fluid's ability to conduct electricity and therefore amplifies the magnetic field, rather than reducing it as earlier experiments had appeared to show. (sciencedaily.com)
