Neodymium Rod Magnet 8 x 40 mm N48
 
Neodymium (NdFeB) is among the strongest magnetic materials and provides substantial holding force for its size. Compared with ferrite, neodymium provides much greater magnetic attraction. The magnet generally has a protective surface coating. N48 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52. The cylindrical design makes it easy to install and useful for attachments, alignment and compact assemblies.
 
A good choice where stronger holding force is needed in a size that is still comfortable to handle. (Ø8×40 mm) For best results, ensure direct contact with the surface. The magnet provides a particularly strong hold on solid steel.
 
Warning: not suitable for children. Swallowed magnets can cause serious injuries. Seek urgent medical attention. Magnets can snap together suddenly, pinch skin and chip or break on impact. Separate them by sliding them apart. Keep them away from bank cards, sensitive electronics and medical devices such as pacemakers.
