Neodymium Ring Magnet 10 x 5 x 5 mm N48
 
Neodymium (NdFeB) is among the strongest magnetic materials. The ring shape is practical because its central hole helps with mounting and alignment. 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 ring magnet fits readily into a recess or around a hole and can be used on a shaft or screw, or as a spacer.
 
This size suits compact applications, including small attachments and simple assemblies on flat metal surfaces. (Ø10/Ø5×5 mm) For best results, ensure direct contact with the surface. The magnet provides a particularly strong hold on solid steel.
 
Warning: keep away from children. Swallowing magnets can be life-threatening. Seek immediate medical attention if swallowing is suspected. 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.
