Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

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 ...

In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...

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

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 ...

Researchers at University of Tsukuba have successfully measured electric fields near the surfaces of two-dimensional layered ...

Scientists have discovered that Earth’s magnetosphere is charged opposite to what was once believed. The area of space influenced by Earth’s magnetic field is called the magnetosphere. Within this ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. A weak region in Earth's magnetic field has ...

The magnetic field that protects our planet is shifting – and one region is fading fast. Over the South Atlantic, a weak spot in Earth’s magnetic shield has grown steadily since 2014. It now stretches ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...
