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 ...

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 ...

Earth’s magnetic field protects the planet from space weather like cosmic radiation and charged particles from the Sun. The ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

With advance warning, however, steps can be taken to reduce the risks. If an electrical grid is running near capacity, for ...

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

The South Atlantic Anomaly (SAA), a known region of Earth’s magnetic field weakness, has been under the observation of the ...

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 ...

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 ...

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

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 ...
