Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...
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 ...
Earth’s magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...
The detailed geomagnetic reversal frequency model reconstructed in this study, geomagnetic polarity time scale (drawn using data from Ogg, 2020, Geologic Time Scale 2020, Elsevier), and the Earth's ...

Scientists discover something strange happened to Earth’s magnetic field, and it lasted 70,000 years
A sediment core from the North Atlantic has revealed that one ofEarth’s magnetic field reversals during the Eocene lasted far longer than expected. Earth’s magnetic field has reversed hundreds of ...
