Solar magnetism is a fundamental driver of dynamic phenomena on the Sun, manifesting in cyclic variations such as sunspot activity, flares, and coronal mass ejections. Central to this process is the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

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 ...

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 ...

More than 50 years ago, NASA landed humans on the Moon — and we brought a piece of it back with us to Earth. That 22 kilograms of rock and dust collected by the Apollo astronauts transformed our ...

Paleomagnetic measurements indicate that a core dynamo probably existed on the Moon 4.2 billion years ago. However, the subsequent history of the lunar core dynamo is unknown.Here we report ...

Dynamo theory By Science News January 1, 1946 at 11:56 pm - More than 2 years ago Physicist Walter M. Elsasser and geophysicist Edward Bullard separately propose between 1946 and 1949 that Earth’s ...

The Earth's global magnetic field is generated in its metallic core, located nearly 3,000 kilometers beneath the planet’s surface. The field has existed on Earth for at least 3.5 billion years and ...
