Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.
Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

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 ...
More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...
Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...
A new radio survey reveals that the Milky Way’s magnetic field is intricate, widespread, and deeply connected to how the galaxy is organized.
New satellite-based analysis explains how energy carried by Alfvén waves moves from Earth’s magnetosphere into the atmosphere to generate auroral light emissions.
Earth’s magnetic field is easy to forget. It doesn’t make noise, it doesn’t flash, and it doesn’t ask for attention. Yet it ...
An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.
