Permanent magnets sit at the heart of the green economy, from wind turbines and electric vehicles to smartphones and industrial robots. For decades, the strongest versions have depended on rare-earth ...
Two researchers who independently developed the neodymium magnet — used in everything from hard disk drives to automobiles — have been awarded the 44th Honda Prize. In 1982, two researchers working ...
The electric vehicle revolution has created market forces to drive all sorts of innovations. Battery technology has ...
In this video I show you what happens when you pour liquid nitrogen on a giant neodymium magnet. I show you how you can increase eddy currents by decreasing the temperature and also how you can ...
For more than a decade we have been reporting on a radical idea from the University of Birmingham that makes recycling rare ...
Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...
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 ...
