Why the ideal magnet remains out of reach
Electron behavior is so complex and entangled, only quantum math may suffice ...
These new iron-nitride magnets are stronger, cleaner to make, and made from domestic iron-salt waste and nitrogen. UPDATE 10/20/2025: Niron Magnetics just broke ground on its commercial magnet ...
Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...
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 ...
Electro-permanent magnets (EPMs) are pretty nifty concepts, and if you aren’t familiar with them, they are permanent magnets with the ability to be electrically switched on or off. Unlike an ...
