Neodymium Ring Magnet 7 x 3 x 8 mm N52 horganyzott
 
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. N52 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. The central hole simplifies mounting and positioning, making it useful for frames, holders and repeatable installations.
 
The Ø7/Ø3×8 mm ring is useful for DIY projects, including lids, boxes, small holders and shaft or screw mounting. (Ø7/Ø3×8 mm) For best results, ensure direct contact with the surface. The magnet provides a particularly strong hold on solid steel.
 
Warning: keep out of reach of children. Swallowing magnets poses a serious risk and requires immediate 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.
