Earth’s magnetic field is probably not reversing [Earth, Atmospheric, and Planetary Sciences]

The geomagnetic field has been decaying at a rate of ∼5% per century from at least 1840, with indirect observations suggesting a decay since 1600 or even earlier. This has led to the assertion that the geomagnetic field may be undergoing a reversal or an excursion. We have derived a...
