Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven by dynamic processes deep within the planet’s core. Drawing on 11 years of ...

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 ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks ...

The physical processes behind the two phenomena are different. When heated, a permanent magnet loses its magnetism because its relatively well-aligned magnetic domains, which are tiny magnets, get ...

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 ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...
