The Earth’s magnetic field experiences unpredictable, rapid, and intense anomalies that are known as geomagnetic jerks. The mechanisms behind this phenomenon had remained a mystery until the recent discovery of a CNRS researcher. Working with a colleague in Denmark, they created a computer model for these geomagnetic jerks, and provided an explanation for their appearance. Their research was published in Nature Geoscience on April 22, 2019.
