As well as a few temporary reversals, the Earth's magnetic field – just like the Sun – can flip over long timescales. During the Brunhes–Matuyama reversal, the magnetic north could have been ...

They found that magnetic reversals significantly weakened field strengths, causing large basins to appear demagnetized. Their findings suggested that Mars's demagnetized basins did not necessarily ...

Such reversals in the Earth's magnetic field, they'd tell you, are, roughly speaking, as common as ice ages. That is, they're terrifically infrequent by human standards, but in geologic terms they ...

This article was originally published with the title “ Reversals of the Earth's Magnetic Field ” in Scientific American Magazine Vol. 216 No. 2 (February 1967), p. 44 doi:10.1038 ...

Indeed, the researchers I spoke with all thought that organisms would be able to adjust to an acute weakening or even complete reversal of the magnetic field. "My gut reaction is it's not going to ...

The last full reversal, the Brunhes–Matuyama event, occurred 780,000 years ago. Around 41,000 years ago, the Laschamp event saw a brief but dramatic magnetic field reversal, lasting only 440 ...

"If the heat extraction becomes less symmetric, this is thought to lead to a magnetic field reversal." A reversal would see the geomagnetic field temporarily weaken—and might also impact ...

Recently, a research team found a new way to control the magnetic reversal in a special material called Co 3 Sn 2 S 2, a Weyl semimetal. The team was led by Prof. Qu Zhe from the Hefei Institutes ...

The time period, which spans 770,000 to 126,000 years ago, started with a reversal of the planet’s magnetic field. Kerry served as The Scientist’s news director until 2021. Before joining The ...

If the Earth's field is disrupted ... The phenomenon "may be linked to the Earth's history of magnetic pole reversals, which have occurred nearly 200 times over the past 100 million years ...
