A team of scientists in South Korea has developed a new way to make high-performance permanent magnets without using costly ...
Before the discovery of the neodymium magnet, the strongest permanent magnet was the samarium–cobalt magnet, which was based on the Sm 2 Co 17 intermetallic phase. However, samarium is expensive ...

Niron Magnetics Clean Earth Magnets: Stronger, Safer, DomesticWeaker hard ferrite (iron-oxide) permanent magnets typically max out at around 0.35 tesla. The world's strongest permanent magnets made of neodymium measure around 1.4‑1.6 teslas. Niron’s ...
and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact, the only thing needed to make them is iron and nitrogen ...
