Neodymium Ring Magnet 17.8 x 6.5 x 10 mm N35
 
A neodymium (NdFeB) ring 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. NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. The ring shape is useful for mounting on a shaft or screw, or for precise alignment and guidance. The central hole helps with these applications.
 
This medium size is suitable for stable, strong attachments while remaining manageable to handle. (Ø17.8/Ø6.5×10 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 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.
