Neodymium Ring Magnet 12 x 8 x 5 mm N35
 
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. 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.
 
At Ø12/Ø8×5 mm, this magnet is useful for magnetic catches, DIY, organisation and lighter attachments to steel. (Ø12/Ø8×5 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. 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.
