Neodymium Ring Magnet 10 x 3 x 5 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, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. 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/Ø3×5 mm) Paint, film or gaps noticeably reduce magnetic attraction. The magnet performs best on a flat, clean surface.
 
Warning: not suitable for children. Swallowed magnets can cause serious injuries. Seek urgent medical attention. Magnetic attraction is strong. Bring magnets together and separate them carefully to avoid pinching injuries and chipping. Keep them away from bank cards, sensitive electronics and medical devices.
