Earth geomagnetic reversal
WebDec 10, 2024 · Called a “geomagnetic field reversal,” this has resulted in the poles swapping positions, with magnetic north becoming magnetic south, and vice versa. The magnetic pole has also undergone what are called “excursions.” During an excursion event, the earth’s magnetic field weakens and begins to drift but does not reverse itself.
