Neodymium Ring Magnet 10 x 6 x 2 mm N35 Diametrically Magnetised
 
A neodymium (NdFeB) ring magnet is very strong. It is magnetised in a strong magnetic field during manufacture, providing high magnetic attraction in a compact size. It is much stronger than conventional ferrite magnets and generally has a protective coating because the material can corrode over time. N35 indicates the magnetic grade, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. diametric magnetic orientation: magnetised radially rather than through the thickness, which is useful in certain technical applications.
 
The Ø10/Ø6×2 mm size suits prototypes and DIY projects, especially applications with shaft or screw mounting. (Ø10/Ø6×2 mm) A good choice for applications requiring a diametric field, including detection, alignment, coupling and rotating systems. 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.
