Certain topological materials could be used in lab tests of the dynamo effect The astrophysical dynamo effect could be tested in the laboratory using electronic materials such as hydrodynamic Weyl ...

Liquid metallic hydrogen is not present naturally on Earth and has only been created in a handful of places. Now scientists are researching the properties of liquid metallic hydrogen to understand how ...

The magnetic field of the Sun is generated by a dynamo effect caused by its convective and rotational movements. It will ...

Billions of years ago, scientists believe that the Moon had a magnetic field, much like Earth’s. But that field shut down at some point — and a team of MIT scientists now say it was because of a ...

The generation of the magnetic field on Earth made scientists wonder if the process occurred in the earliest days of the planet. The magnetic field generation was explained by a mechanism known as the ...

Weird materials called Weyl metals might reveal the secrets of how Earth gets its magnetic field. The substances could generate a dynamo effect, the process by which a swirling, electrically ...

This so-called dynamo effect creates cosmic magnetic fields, like those found on planets, moons and even asteroids. Over the coming years, a globally unique experiment, in which a steel drum ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Black holes are well known for swallowing any matter that strays near them – but new results show that they may also supply energy to the gas and dust around them. X-rays emitted by the debris around ...

The Sun’s activity is determined by the Sun’s magnetic field. Two combined effects are responsible for the latter: The omega and the alpha effect. Exactly where and how the alpha effect originates is ...
