How tornado-shaped flow in a dynamo strengthens the magnetic field
Washington DC (SPX) May 24, 2017
The massive, churning core of conducting liquids in stars and some planets creates a dynamo that generates the planetary body's magnetic field. Researchers aim to better understand these dynamos through computer simulations and by recreating them in the laboratory using canisters of rapidly spinning, liquid sodium. A new simulation based on the von-Karman-Sodium (VKS) dynamo experiment, run jointly by the French Atomic Energy Commission (CEA), the National Center for Scientific Research (CNRS) and ... read more
