The last reversal of Earth's magnetic field took far longer than was previously thought, scientists have discovered. By analyzing ancient volcanic rocks, researchers found the Matuyama-Brunhes ...

The Earth's magnetic field surrounds our planet like an invisible force field—protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ends of the magnetosphere, which surrounds the Earth like a giant, invisible ...

A team of researchers used volcanic records to study Earth's last magnetic-field reversal, which occurred about 780,000 years ago.They found that this flip may have taken much longer than ...

Every several hundred thousand years or so, Earth's magnetic field dramatically shifts and reverses its polarity. Geologist found that the most recent field reversal, some 770,000 years ago, took ...

In their paper published today in Science Advances, Brad Singer of the University of Wisconsin–Madison and his colleagues calculate that Earth’s last magnetic field reversal took roughly ...

Every several hundred thousand years or so, Earth's magnetic field dramatically shifts and reverses its polarity. New work from University of Wisconsin-Madison geologist Brad Singer and his ...

During the Brunhes–Matuyama reversal, the magnetic north could have been as far south as the equator. You probably don't worry about the Earth's magnetic fields too much, assuming you don't have ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

The Earth's magnetic field is essential to life as we know it. ... According to NASA, the Laschamp event, occurred about 41,000 years ago, which caused a short reversal of Earth's magnetic field.

Earth’s magnetic field seems steady and true — reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North Pole is […] ...

But the Earth's magnetic fields are not as fixed as you might think. "We know that over the past 200 years, the magnetic field has weakened about 9 percent on a global average.
