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 ...

A newly discovered "doughnut" in Earth's core could influence the planet's magnetic field. In a new study, researchers observed the doughnut-shaped structure for the first time by looking at ...

The plasma is confined by magnetic fields in a doughnut-like torus shape, but heavier ‘exhaust’ elements from the so-called scrape-off layer (SOL) hit the divertor plate. “Plasma generates ...

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 ...

Using data collected by NASA’s Juno spacecraft as it flew past Jupiter’s highly volcanic moon Io in late 2023 and again in ...
