Alnico Magnets Explained: Grades, Strength and Heat Limits
Alnico magnets were the strongest permanent magnets in the world for about four decades, until rare earth magnets arrived in the 1970s. They are no longer the strongest, but they have not gone away. Alnico still does two things better than any other common magnet: it survives extreme heat, and its field barely drifts as…

Neodymium Magnets (NdFeB) Explained: Grades, Strength and Limits
Neodymium magnets are the strongest permanent magnets available. A piece the size of a coin can lift several kilograms, and larger ones drive the motors of electric cars and the generators of wind turbines. Their full name is neodymium iron boron, usually shortened to NdFeB. This guide explains what they are made of, how they…

Dysprosium: Uses, Supply and the Push for Dy-Free Magnets
Dysprosium (Dy) is the heavy rare earth that keeps EV and wind turbine magnets working when they get hot. Here is what it does, why its supply is so fragile, and how magnet makers are learning to use less of it, or none at all.
