Strongest Isn’t Smartest: A Field Guide to Picking the Right NdFeB Magnet
Engineers default to the highest-grade magnet on the datasheet more often than they should. For NdFeB (neodymium-iron-boron) magnets, that instinct backfires the moment heat enters the picture. Grade selection is a tension between two forces: magnetic strength and temperature resistance. Lose that tension and the failure isn’t a dramatic snap. It’s a slow bleed of […]
