Every few hundred thousand years, Earth’s magnetic poles flip, turning north into south and south into north. These geomagnetic reversals can take thousands of years, but shorter disruptions—called ...

Paleomagnetic records are the remnant magnetisation preserved in rocks, sediments and speleothems that faithfully archive the orientation and intensity of the Earth’s magnetic field through geological ...

Earth’s magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the ...

Earth's magnetic field protects us from the dangerous radiation of space, but it is not as permanent as we might believe. Scientists at the European Geosciences Union General Assembly present new ...

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 ...

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 ...
