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 ...
Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...
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 flips often, and some reversals drag on 70,000 years
Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...
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 ...
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 ...
