Neodymium Disc Magnet 10 x 7 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 × 7 mm, this magnet is suitable for more demanding workshop attachments, including holders, jigs, removable assemblies and technical projects. Even a small gap caused by thick paint, tape or an uneven surface noticeably reduces holding force. It performs best on solid steel.
 
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 medical devices and objects sensitive to magnetic fields, including cards and electronics.
