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

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

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 ...

Did Earth’s magnetic field help make life possible on the planet? A new NASA-funded study suggests the answer may lie deep in ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Researchers have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation ...

Aditya-L1's observations reveal unusual dawn-time geomagnetic disturbances during strong solar storms, enhancing our understanding of solar wind effects.

Earth’s magnetic field and atmospheric oxygen appear to have moved in sync for half a billion years, pointing to a surprising connection between the planet’s deep interior and life-supporting ...

Scientists have used state-of-the-art 3D printing and microscopy to provide a new glimpse of what happens when taking magnets to three-dimensions on the nanoscale – 1000 times smaller than a human ...
