Every few hundred thousand years or so, the Earth's north and south magnetic poles switch places. No one knows what triggers these geomagnetic field reversals, but a team in France has now reproduced ...

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 ...

There’s a moment in any movie or cartoon featuring a mad scientist when they flip a switch or mix two chemicals and boom, their lab explodes and smoke billows out the windows and doors. In reality, at ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

This is a computer simulation of gas (in yellow) falling into a black hole (too small to be seen). Twin jets are also shown with magnetic field lines. Disclaimer: AAAS and EurekAlert! are not ...

The rules about what makes a good magnet may not be as rigid as scientists thought. Using a mixture containing magnetic nanoparticles, researchers have now created liquid droplets that behave like ...

Bizarre magnetic behavior that was predicted by a famous physicist more than 80 years ago has finally been demonstrated in the lab, according to a new study. The behavior of an electron in response to ...

Ripped from the pages of a sci-fi novel, physicists have crafted a wormhole that tunnels a magnetic field through space. "This device can transmit the magnetic field from one point in space to another ...

For a variety of obvious reasons, it's impossible to reproduce the exact environment in which galaxies form. The lack of direct experimental tests for a the models astrophysicists use creates a ...
