Neodymium Disc Magnet 15 x 5 mm N35
 
Neodymium (NdFeB) is among the strongest magnetic materials, even in small sizes, and its stability makes it useful for many practical applications. Neodymium is much stronger than ferrite, and its protective coating helps prevent corrosion. N35 indicates the magnetic grade; a higher number generally means a stronger magnet, with grades commonly ranging from N35 to N52.
 
At Ø15 × 5 mm, this magnet is suitable for more demanding workshop attachments, including holders, jigs, removable assemblies and technical projects. 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: 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.
