Magnetic field reversal is a fascinating topic. You are brought up to think that the compass, pointing to the north, is an ...

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

A team led by Japan’s National Institute of Polar Research has identified four time windows in the last 160 million years where Earth’s record of magnetic pole reversals appears to be missing entries.

Sometimes the geologic record obscures evidence of these important reversals in field direction, but statistical techniques ...

The planet's magnetic North Pole, where compasses point, has been unexpectedly moving toward Russia. While shifting is not a rare occurrence, the pole is moving both faster and differently than it was ...

Japanese researchers say they are closing in on the mystery of Earth’s “missing” geomagnetic polarity reversals, identifying ...
