Neodymium Ring Magnet 20 x 7 x 2 mm N35
 
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. N35 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. 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.
 
At Ø20/Ø7×2 mm, this magnet provides a strong hold for workshop use, assembly, alignment and technical projects. (Ø20/Ø7×2 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 bank cards, sensitive electronics and medical devices.
