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 ...

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

For decades, scientists have been trying to understand why some rocks on the moon are strongly magnetized even though the moon has no magnetic field today. Moon rocks brought to Earth during NASA's ...

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

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 ...

In a paper published in Earth and Planetary Physics, an international team of researchers studied the magnetic properties of ...

"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 ...
