The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

As the iron and nickel inside our planet shift, so does Earth's magnetic field, meaning the North (and South) Poles are also ...

Earth's magnetic field is shaking things up once again. Sloshing liquid iron in Earth's outer core—which lies roughly 1,900 miles (3,200 kilometers) below us—generates our planet's protective magnetic ...

Yale researchers may have solved a longstanding puzzle as to why certain metallic meteorites show traces of a magnetic field — a finding that may shed light on the formation of magnetic dynamos at the ...

Mercury’s core may be wearing a metal jacket. New experiments suggest the planet’s innards stay warm thanks to an insulating layer of iron sulfide, which could help to explain how the small world has ...

About 3,000 years ago in ancient Mesopotamia, brickmakers imprinted the names of their kings into clay bricks. Now, an analysis of the metal grains in those bricks has confirmed a mysterious anomaly ...
