Researchers discovered a donut-shaped region at the ceiling of the outer core This lighter region helps stir the liquid metal which generates the magnetic field Scientists have uncovered a vast ...

Researchers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory are harnessing the power of computers to ...

This generates a poloidal magnetic field that bends the plasma current into a circle (green vertical circle). Bending the column into a circle prevents leakage and doing this inside a doughnut-shaped ...
