Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new ...

5 million years ago. This southeastern Oregon location provides one of the most startling examples of how quickly Earth's magnetic field can flip. A series of overlapping Miocene-age basaltic lava ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes itself over thousands of years before settling again. For decades, researchers ...

The geomagnetic field, generated by the convecting motions of Earth’s liquid outer core, is a fundamental facet of our planet’s evolution. Its long‐term behaviour is recorded in rocks through the ...

The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal.

Evidence suggests that the planet may be in the opening strains of a geomagnetic chicken dance, the likes of which we haven't seen for almost a million years. Share on Facebook (opens in a new window) ...

The Earth's magnetic field is generated by the complex interplay of convective flows in its liquid outer core, a process commonly referred to as the geodynamo. The dynamics of this magnetic field are ...
