Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

A new video shows how Earth's magnetic field weakened and warped before temporarily flipping during a recent "polar reversal event." When you purchase through links on our site, we may earn an ...

An animation showing magnetic field instabilities in two jets of radiation and matter beaming from a supermassive black hole (center). The magnetic field (white) is twisted by the black hole's spin.

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds.

For decades, scientists have puzzled over a curious phenomenon: the Moon’s surface rocks show strong signs of magnetism, despite the fact that the Moon doesn’t have a global magnetic field today. Now, ...

<p>Simulation of a possible quadrupole magnetic field configuration for a pulsar with hot spots in only the southern hemisphere. <p>View animated GIF: <a target ...

Our planet’s magnetic field is “singing.” The European Space Agency just released a recording of the frequencies generated as a solar storm collided with Earth’s magnetic field. It was released ...
