At the same time, he believed there was a need for new permanent magnets that combined rare-earth elements and iron. “Iron is more abundant, cheaper, and has a stronger magnetic moment than ...

In fact, the only thing needed to make them is iron and nitrogen, plus an understanding of crystal structure and some engineering ingenuity. To start things off, what even is a permanent magnet?

Neodymium-iron-boron is the strongest permanent magnet material in wide-scale use today Name a technology that is all around us, underpins our modern way of living but is hardly recognised for its ...
