Neodymium Ring Magnet 29 x 12.5 x 15 mm N48
 
An NdFeB (neodymium) ring magnet provides high magnetic attraction for its size and fits readily into various holders and components. Alongside high magnetic attraction, the surface coating helps improve durability. N48 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52. The ring magnet fits readily into a recess or around a hole and can be used on a shaft or screw, or as a spacer.
 
Larger sizes provide substantial magnetic attraction, suitable for strong attachments and robust projects, with careful handling. (Ø29/Ø12.5×15 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 quickly and pinch fingers. They are hard but brittle, so do not allow them to collide. Keep them away from bank cards, sensitive electronics and medical devices.
