Since their relatively recent appearance on the commercial scene, rare-earth magnets have made quite a splash in the public imagination. The amount of magnetic energy packed into these tiny, shiny ...

Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the ...

The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged objects ...

Niron Magnetics aims to use cheap, widely available materials to make magnets for EVs and wind turbines. The motor in your vacuum cleaner and the one in your electric vehicle likely have at least one ...

Creating strong permanent magnets without using so-called rare earth elements is an ongoing topic of research. An interesting contestant here are iron nitride magnets (α”-Fe 16 N 2), which have the ...

China controls about 90% of the entire global supply of rare earth magnets, including their mining and refining. That means that most of the neodymium, dysprosium, and terbium that end up in EV motors ...

Scientists from the Ural Federal University and the Ural Branch of the Russian Academy of Sciences are determining the optimal conditions for 3D printing of permanent magnets from hard magnetic ...

What was iron doing at life's birth? : life without oxygen -- Catastrophe : the arrival of oxygen -- Grabbing and storing : controlling iron -- The smallest living magnets : avoiding oxygen -- ...
