Neodymium Ring Magnet 35 x 20 x 8 mm N35
 
Neodymium (NdFeB) is among the strongest magnetic materials. The ring shape is practical because its central hole helps with mounting and alignment. Alongside high magnetic attraction, the surface coating helps improve durability. N35 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.
 
Larger sizes provide substantial magnetic attraction, suitable for strong attachments and robust projects, with careful handling. (Ø35/Ø20×8 mm) Holding force depends strongly on the thickness and condition of the metal surface. It is greater on thick steel and weaker on thin sheet metal.
 
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 medical devices, cards and sensitive electronics.
