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 ...

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, ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

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 ...

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 ...

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 ...

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 ...
