The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By ...

Some planets take the expression "you're your own worst enemy" to the extreme — triggering stellar flares from their own ...

There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis suggested that in the first billion years, when the Moon was covered in molten ...

Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms.

The near $16-million reduction would impact "our national security, global positioning, and economic growth," wrote U.S.Rep.

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

According to the ESA, “Our magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 1,864 miles beneath our feet.

Such disturbances can come from the sun's magnetic field, for example, particularly during periods of heightened solar activity, such as sunspots and solar flares, but also from other sources.

During this event, Earth’s magnetic field rapidly weakened and the poles flipped, only to reverse again 500 years later. ... So that would be an example of coincidental climate change. ...

The magnetic field produced by a microwave oven from an inch away, for example, is only about two gauss. Power tools, from the same distance, will produce up to about eight to ten gauss. So yeah, ...
