Neodymium Disc Magnet 12.5 x 10 mm N35
 
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. N35 indicates the magnetic grade; NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets.
 
At Ø12.5 × 10 mm, this magnet is suitable for more demanding workshop attachments, including holders, jigs, removable assemblies and technical projects. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
 
Warning: keep away from children. Strong attraction can cause pinching injuries, and the magnet can chip easily. Store magnets with spacers and avoid impacts. Keep them away from medical devices and objects sensitive to magnetic fields, including cards and electronics.
