Neodymium Disc Magnet 25 x 3 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. Compared with conventional ferrite magnets, neodymium provides much greater magnetic attraction. A protective coating helps improve durability. N48 indicates the magnetic grade; NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets.
 
The Ø25 × 3 mm size provides a strong, stable hold for workpiece holding, workshop organisation and everyday practical applications. 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, sensitive electronics and medical devices.
