From PPPL: Electric current is everywhere, from powering homes to controlling the plasma(link is external) that fuels fusion(link is external) reactions to possibly giving rise to vast cosmic magnetic fields. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that electrical currents can form in ways not known before. The novel findings could give researchers greater ability to bring the fusion energy that drives the sun and stars to Earth. https://www.pppl.gov/news/2020/09/researchers-find-unexpected-electrical-current-could-stabilize-fusion-reactions
