If Earth’s magnetic field resembles that of a bar magnet, Jupiter’s field looks like someone took a bar magnet, bent it in half and splayed it at both ends. The field emerges in a broad swath across ...

China has quietly crossed a threshold in magnet technology that most people will never see but many will eventually feel. By ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...

Scientists measured a chorus wave emerging from an unexpected place, and confirmed a key piece of a theory about how these strange waves form.

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

A long-standing weak spot in Earth's magnetic field is getting weirder, and it may be splitting into two distinct zones of weakness. The South Atlantic Anomaly is a section of Earth's magnetic field ...
