What You Get
Neodymium N42 rare earth magnet, nickel coated, gold coloured, 1.8mm thick and 22mm diameter
How does it work?
Neodymium magnets are made from a mix (alloys) of rare earth elements: neodymium, iron and boron (Nd2Fe14B), and are the strongest type of permanent magnets.
Test the strength of this beauty by using our metal slinky. Your students might be very surprised when this relatively small magnet lifts many more coils than much larger, weaker magnets like common ferrites.
Rare earth magnets are brittle and can chip or break when dropped on a hard surface or allowed to smash together with another magnet or a piece of metal. These magnets must be used with care, they can disrupt sensitive electronic equipment like computers, and can leap together from a distance and pinch fingers.
