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 ...

The weak spot, known as the South Atlantic Anomaly, was identified in the 19th century and expanded in recent years.

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

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 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 ...

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 ...
