Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Magnetic signatures hidden inside rocks tell us a lot about Earth's magnetic field and the way continents and tectonic plates have shifted across millennia – but for some periods, the geological ...

Understand the magnetic field of two long wires with this detailed physics example! Learn how currents interact, how to calculate the resulting magnetic field, and visualize the principles behind ...

Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better understand this mechanism, the team led by Argovia-Professor Martino Poggio from ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

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

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

AMES, Iowa – A tiny, solid sample of a drug, complete with active and inactive ingredients, spun at 50,000 revolutions per ...
