Neodymium Ring Magnet 9.8 x 7 x 5 mm N48
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. N48 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.
The Ø9.8/Ø7×5 mm ring is useful for DIY projects, including lids, boxes, small holders and shaft or screw mounting. (Ø9.8/Ø7×5 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.
