Neodymium Rod Magnet 3 x 6 mm N48
 
A neodymium (NdFeB) cylinder magnet is very strong. It is magnetised in a strong magnetic field during manufacture, providing high magnetic attraction in a compact size. It is much stronger than conventional ferrite magnets and generally has a protective coating because the material can corrode over time. N48 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. The cylindrical shape is practical: it fits readily into a hole or recess and provides good contact on flat metal surfaces.
 
Suitable for smaller projects and discreet attachments, and easy to incorporate into an assembly. (Ø3×6 mm) For best results, ensure direct contact with the surface. The magnet provides a particularly strong hold on solid steel.
 
Warning: keep out of reach of children. Swallowing magnets poses a serious risk and requires immediate 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.
