Neodymium Ring Magnet 19.8 x 6.2 x 15 mm
 
An NdFeB (neodymium) ring magnet provides high magnetic attraction for its size and fits readily into various holders and components. Compared with ferrite, neodymium provides much greater magnetic attraction. The magnet generally has a protective surface coating. The N indicates the magnetic grade. NdFeB grades commonly range from N35 to N52. 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 is a strong magnet. Handle it carefully near other magnets and metal objects. (Ø19.8/Ø6.2×15 mm) Paint, film or gaps noticeably reduce magnetic attraction. The magnet performs best on a flat, clean surface.
 
Warning: keep out of reach of children. Swallowing magnets poses a serious risk and requires immediate medical attention. Magnets can snap together suddenly, pinch skin and chip or break on impact. Separate them by sliding them apart. Keep them away from bank cards, sensitive electronics and medical devices such as pacemakers.
