A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new ...

On Sunday, they announced the successful generation of a steady magnetic field of 351,000 gauss using a fully superconducting ...

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 ...

Ancient bricks may be key to understanding Earth’s variable magnetic fields. Scientists examined the iron oxide levels of 3,000-year-old bricks to understand the level of magnetism the bricks were ...

Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study. An international team of researchers has used behavioral experiments to show that two different ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Some inventions are so simple that it’s hard to improve them. The magnetic compass is a great example — a magnetized needle, a bit of cork, and a bowl of water are all you need to start navigating the ...
