Question

What magnet is stronger than Neodymium?

Answer 1

Neodymium:

• Neodymium is a rare earth magnet.
• Iron Nitride (${\mathrm{Fe}}_{16}{\mathrm{N}}_2$), which is produced by combining Iron ($\mathrm{Fe}$) and Nitrogen ($\mathrm{N}$) is considered a stronger magnet than Neodymium $\left({\mathrm{Nd}}_2{\mathrm{Fe}}_{14}\mathrm{B}\right)$.
• Iron Nitride is a very strong permanent magnet that does not require any rare-earth elements, such as neodymium.
• The theoretical magnetic energy product for Iron nitride is more than twice the maximum magnet energy product for a rare-earth neodymium magnet.
• The cost of iron and nitrogen used in the making of Iron Nitride is much cheaper than rare earth magnets.

Hence, the Iron Nitride magnet is stronger than Neodymium.
