Neodymium Ring Magnet 8 x 3 x 1 mm N48
 
Neodymium (NdFeB) is among the strongest magnetic materials. The ring shape is practical because its central hole helps with mounting and alignment. Compared with ferrite, neodymium provides much greater magnetic attraction. The magnet generally has a protective surface coating. N48 indicates the magnetic grade, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. The central hole simplifies mounting and positioning, making it useful for frames, holders and repeatable installations.
 
Its small size suits precision work, including model making, prototypes, sensors, electronics and experiments. (Ø8/Ø3×1 mm) For best results, ensure direct contact with the surface. The magnet provides a particularly strong hold on solid steel.
 
Warning: keep away from children. Swallowing magnets can be life-threatening. Seek immediate medical attention if swallowing is suspected. 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 such as pacemakers.
