“Cosmic magnet” recreated in lab as alternative to rare earths
Rare earth elements are a key part of electronic and mechanical devices, but they’re in short supply. Now, scientists have found a way to recreate a promising alternative – a “cosmic magnet” that normally takes millions of years to form in meteorites can now be cooked up in the lab in seconds.Many of our electronic devices and mechanical components rely on rare earths. That’s especially true for greener technologies – high-performance magnets, which are vital for everything from wind turbines to electric cars, require…
