Neodymium Disc Magnet 1 x 0.5 mm N48
 
Neodymium (NdFeB) is among the strongest magnetic materials, even in small sizes, and its stability makes it useful for many practical applications. Compared with conventional ferrite magnets, neodymium provides much greater magnetic attraction. A protective coating helps improve durability. The N48 magnet belongs to the NdFeB family, commonly ranging from N35 to N52; a higher number generally means greater magnetic attraction.
 
The small size suits precision tasks such as model making, prototypes, electronic components and very discreet attachments. 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. Two magnets can snap together quickly, pinch fingers and crack or chip. Use spacers for storage and take care when separating them. Keep them away from bank cards, sensitive electronics and medical devices.
