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 ...

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

New satellite-based analysis explains how energy carried by Alfvén waves moves from Earth’s magnetosphere into the atmosphere to generate auroral light emissions.

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth's magnetic fields, which ...

Scientists at the University of New Hampshire have unleashed artificial intelligence to dramatically speed up the hunt for next-generation magnetic materials. By building a massive, searchable ...
