For years, NASA has monitored a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the ...

The Magnetic Shield That Protects Our Climate Earth is surrounded by an immense magnetic field, called the magnetosphere.

Geologists discovered ancient rocks in Greenland that preserve the oldest known traces of Earth’s early magnetic field.

Earth’s magnetic field protects life from harmful cosmic radiation. But sometime between about 590 million and 565 million years ago, that security blanket seems to have been much thinner — with ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

What if Earth had Jupiter’s magnetic field strength? Explore how stronger magnetic protection would affect life, technology, ...

Earth is not heading toward a doomsday reversal of its magnetic field, new research assures. The planet’s magnetic field is about 10 percent wimpier today than when physicists began keeping tabs on it ...

A newly discovered mechanism known as microtube implosion could make it possible to generate magnetic fields 1000 times stronger than any yet seen in the laboratory. According to the researchers who ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...
