For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

High magnetic fields are a vital tool in many areas of science and technology that impact our everyday lives, from medical diagnostics through magnetic resonance imaging (MRI) to drug discovery ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to geothermal heat. Now a small group of physicists says Earth’s own magnetic ...

The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed. When you ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

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 ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

Invisible yet vital, Earth’s magnetic field plays a crucial role in shielding the planet from harmful solar radiation and cosmic particles. Generated deep within the Earth’s molten outer core, this ...
