The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years. This has sparked many questions and concerns about the implications of such ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

In 2008, Erez Ben-Yosef unearthed a piece of Iron Age "trash" and inadvertently revealed the strongest magnetic-field anomaly ever found. Ben-Yosef, an archaeologist at Tel Aviv University, had been ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Protective force fields exist and you’re already living inside one. About 1,800 miles beneath the ground you’ll reach the border of Earth’s outer core, a subterranean ocean of liquid iron and nickel 1 ...
