Today's computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to ...

This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New ...

Researchers are developing magnonic processors that use magnetic spin waves instead of electric current to process data.

Forty-two thousand years ago, Earth’s magnetic field collapsed - the sky turned electric, radiation burned the surface, and humanity was forced underground. Scientists call it the Adams Event, a ...

Researchers from the MIT Media Lab have developed an antenna—about the size of a fine grain of sand—that can be injected into ...

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 ...

Scientists have discovered that a 'weak spot' in Earth's magnetic field is growing at an alarming rate. Known as the South Atlantic Anomaly (SAA), the region has expanded by an area nearly twice the ...
