Researchers have identified an unexpected link between atomic magnetism and carbon mobility in steel. Researchers at 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 ...

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 ...

Materials scientists from The Grainger College of Engineering have provided the first quantitative explanation for a phenomenon first observed in iron in the 1970s.
