Neodymium Disc Magnet 8 x 1.5 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. Its magnetic attraction is much greater than that of ferrite magnets, and a surface coating protects it against corrosion. N48 indicates the magnetic grade; a higher number generally means a stronger magnet, with grades commonly ranging from N35 to N52.
The Ø8 × 1.5 mm size is suitable for DIY projects, small holders, catches and temporary attachments to steel. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
Warning: not suitable for children. Strong magnets can snap together suddenly, causing pinching injuries, and may break. Bring them together and separate them carefully. Keep them away from bank cards, hard drives, sensitive electronics and medical devices.
