Neodymium Disc Magnet 14 x 8 mm N48
 
A neodymium magnet (NdFeB) is small but very strong. It is made from a special alloy and magnetised in a strong magnetic field during manufacture. It is noticeably stronger than conventional ferrite magnets and generally has a protective coating because the material is prone to corrosion. The N48 magnet belongs to the NdFeB family, commonly ranging from N35 to N52; a higher number generally means greater magnetic attraction.
 
At Ø14 × 8 mm, this magnet provides a strong hold for quick assemblies, tools, DIY and general applications on steel. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
 
Warning: keep out of reach of children. Magnets can snap together suddenly, pinch skin and chip or break on impact. Handle them carefully when bringing them together or separating them. Keep them away from bank cards, sensitive electronics and medical devices.
