Neodymium Rod Magnet 4 x 8 mm N35 Diametrically Magnetised
 
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. N35 indicates the magnetic grade, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. The cylindrical design makes it easy to install and useful for attachments, alignment and compact assemblies.
 
The Ø4×8 mm cylinder is useful for DIY projects, including lids, boxes, small holders and quick attachments. (Ø4×8 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.
