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 ...

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 ...

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, ...

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 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 ...

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 ...

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 ...

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 ...

Although the magnetic field of Mars hasn't been in effect for billions of years, the evidence it left behind may suggest that the planet's core is entirely liquid. Magnetic imprints still exist on ...
