A geomagnetic field is generated in Earth's interior and extends into outer space to protect Earth from cosmic radiation and the charged particles of solar wind. The magnetic field is generated by the ...

The Earth’s magnetic field is generated by convective motions in the liquid outer core, a process known as the geodynamo. Over geological time, this field has undergone continual change in intensity ...

Schematic of the Earth’s magnetic field (upper left), history of geomagnetic reversals inferred from the remanent magnetization of ocean-floor rocks (lower left; compiled from data in Ogg, Geologic ...

New models of how the geomagnetic field that shields the Earth's atmosphere from cosmic rays has changed over tens of thousands of years can help us understand how the climate has changed over a ...

In the South Atlantic, stretching from Chile to South Africa, there’s a wide span where the Earth’s magnetic field isn’t quite in line with the rest. Here, at what’s called the South Atlantic Anomaly, ...

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...

Researchers in France have developed a new model of Earth’s magnetic field that includes a simple explanation for why it has flipped direction many times throughout Earth history. Most geophysicists ...
