Physicists weren’t sure why Moon rocks brought back during the Apollo missions are more strongly magnetized than models predict ...

Small magnetic waves have been discovered at Earth's core, with each oscillation working on a seven year cycle. Earth's magnetic field is generated by electric currents generated by the movement of ...

Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth’s core, 1,800 miles underground. The magnetic field strength ...

A new study reveals Earth's magnetic flips can last up to 70,000 years, exposing life to increased solar radiation.

Scientists have uncovered a previously unknown doughnut-shaped region within Earth's outer core, offering new insights into the dynamics of the planet's magnetic field. Located thousands of kilometers ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...
