Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature.

Advanced modeling has revealed an Australia-shaped magnetic anomaly beneath the country's Northern Territory that holds ...

Unlike Earth, the Moon doesn't have much of a magnetic field – and yet, a strange pile of rocks on the far side seems mysteriously magnetized. A new study suggests that a major cataclysm, over and ...

The recent Australia Magnetic Anomaly mapping was done using regional aeromagnetic data gathered during the Northern ...

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...

This photo shows an example of the 3.7 billion year-old banded iron formation found in the northeastern part of the Isua Supracrustal Belt. Geologists at MIT and Oxford University have uncovered ...

Ancient volcanic rocks reveal how two giant hot regions beneath Africa and the Pacific have shaped Earth's magnetic shield.

Where did the moon’s magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft picked up signs of a high magnetic field in lunar surface rocks. The moon ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...
