What is a Super Magnet?
A “super magnet” is generally a slang term for neodymium magnets, the strongest permanent magnets known. It can also be a term for a powerful electromagnet, like the type used in hospitals for fMRI (functional magnetic resonance) imaging. Both magnets are much stronger than typical ferrite bar magnets, and can be a health danger for those wearing pacemakers. Neodymium magnets are also so strong that one can be hurt just by playing with large samples of them — the force they generate when coming together can be strong enough to pierce human skin. The cost of neodymium magnets is about $USD 44 (US Dollars) per kilogram ($97 USD per pound). The most well-known and widespread form of super magnet are neodymium magnets, made of an alloy of neodymium, iron, and boron — Nd2Fe14B. They only became widely available as of the 90s. Unlike ferrite magnets, which are a dull gray, a neodymium super magnet is shiny and silvery, like polished stainless steel. Neodymium magnets can hold 1300 times the
