As another poster said, iron's theoretical max is twice the currently available rare earth strength. It's apples and oranges.

- iamgopal 9y agoTwice then theoritical max of rare earth ?
- rplst8 9y agoIt looks like the theoretical max for rare earth is not that straight forward. See the BH(max) column here: https://en.wikipedia.org/wiki/Rare-earth_magnet#Magnetic_properties https://en.wikipedia.org/wiki/Rare-earth_magnet#Magnetic_pro...
- tremon 9y agoMaybe apples and oranges when purely considering the material properties, but I think the point being made is that FeN could replace Nd in all currently applicable technologies.
- Sean1708 9y agoFrom a quick google search it does indeed look like the theoretical BHmax of rare-earth magnets is about 60 MGOe, so I think that might just be poor wording from the article. That said, I would agree that we should be waiting to sing their praises until they can beat rare-earth magnets in practice.
