Neodymium Disc Magnet 10 x 3 mm N48
 
A neodymium magnet (NdFeB) is a very strong magnet produced by aligning the alloy particles in a strong magnetic field during manufacture. Neodymium is much stronger than ferrite, and its protective coating helps prevent corrosion. N48 indicates the magnetic grade; a higher number generally means a stronger magnet, with NdFeB grades commonly ranging from N35 to N52.
 
At Ø10 × 3 mm, this magnet is useful for magnetic catches, workshop organisation, DIY projects and lighter attachments to metal surfaces. For good results, use a clean metal surface that is as thick as possible. Any gap caused by thick paint or an uneven surface reduces holding force.
 
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 bank cards, hard drives, sensitive electronics and medical devices.
