Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – raising big questions about how long these reversals actually take, and how we ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Head, Research and Development Section, Computer Dept. Raytheon Manufacturing Co., Waltham, Mass. MAGNETIC core circuits can be found performing the computer functions of storage, manipulation, ...

No matter how memory technology marches on, magnetic core memory is still cool. Radiation-hard, nonvolatile, and so pretty. What’s there not to love? [Mark Nesselhaus] is no stranger to fun ...

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 ...

Eventually, the blob of molten material beneath Canada split in two and the stronger one slowly shifted toward the blob beneath Siberia. This spurred the magnetic north pole to slip closer and closer ...

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 ...
