Heat transport in electrically conducting fluids subjected to a magnetic field is relevant to studying anything from liquid metal planetary cores to liquid metal cooling systems for nuclear fusion reactors. Despite the relevance of these flows, relatively little is currently known about them. Here, we present simulations which show the various states which occur in such a system, with different states found by applying magnetic fields with different strengths or changing the temperature difference imposed on the box. A deeper fundamental understanding of these states could lead to more efficient cooling systems that transport more heat at a reduced energy cost.
