magnetic field

Scientists think Cha 1107-7626 sudden growth is driven by magnetic fields, which helped guide more gas and dust towards the rogue planet’s surface.

At its heart lies a supermassive black hole that draws in matter from nearby space and propels some of it outward in colossal plasma jets filled with radiation, heat, magnetic fields, and heavy particles.

The magnetic fields at the poles are vital to the Sun's global dynamo process and may act as "seed fields" that shape the next solar cycle, defining the overall solar magnetic structure.

Earth is lucky to have a magnetic field that shields the planet -- and everything living on it -- from dangerous cosmic radiation.

This transformation can be triggered and controlled remotely with a magnetic field, opening possibilities for a wide range of practical uses.
