Neodymium Ring Magnet 7.5 x 3.9 x 1,2 mm N35
 
An NdFeB (neodymium) ring magnet provides high magnetic attraction for its size and fits readily into various holders and components. 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 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. (Ø7.5/Ø3.9×12 mm) Holding force depends strongly on the thickness and condition of the metal surface. It is greater on thick steel and weaker on thin sheet metal.
 
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 medical devices, cards and sensitive electronics.
