Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

Pigeons may sense Earth’s magnetic field using their inner ear, sending signals to brain areas that help with navigation and ...

Nearly 200 years ago, a scientist named Michael Faraday tried experimenting to see whether Earth's magnetic field could help humans generate electricity for practical purposes. He concluded that ...

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 ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Two enormous, supercontinent-sized 'islands' buried deep within the mantle have been revealed to have fundamental differences—contrary to previous assumptions—and they may even lead to Earth's ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

New research reveals how cryptochromes, magnetite, and electromagnetic induction help animals detect magnetic cues and find ...

Earth spins, shifts, and now… flips? Our planet’s gymnastics routine continues underneath our feet nearly every day, but researchers at the Helmholtz Centre for Geosciences in Germany recently mapped ...
