Many grade school students perform a simple physics experiment by using iron fillings to outline a magnetic field. Seizing on their inner-child, physicists at the Max Planck Institute for Quantum ...

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 ...

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

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

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 ...

This photo shows an example of the 3.7 billion year-old banded iron formation found in the northeastern part of the Isua Supracrustal Belt. Geologists at MIT and Oxford University have uncovered ...

The intensely hot interior of planets isn’t somewhere you’d expect to find snow, but scientists do suspect that “iron snow” falls on the Earth’s core. Now, a new study has modeled the dynamics in the ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...

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 ...

Ancient bricks from Mesopotamia have helped confirm a mysterious anomaly in Earth's magnetic field that occurred 3,000 years ago, a new study finds. Brickmakers baked the bricks, which were imprinted ...
