Push two magnets together and you’ll set off an avalanche of activity, forcing atoms on each magnet to align their polarity with the intruding magnetic field. It may sound like a party trick for ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

June 8 (UPI) --A South Atlantic rapid geomagnetic field decrease known as the South Atlantic Anomaly led to speculation that Earth's magnetic polarity was reversing. But a new study, published this ...

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.

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Scientists have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light. (Nanowerk ...

Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity ...
