Neodymium Ring Magnet 12 x 8 x 3 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. 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.
The Ø12/Ø8×3 mm ring is useful for DIY projects, including lids, boxes, small holders and shaft or screw mounting. (Ø12/Ø8×3 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 suddenly, pinch skin and chip or break on impact. Separate them by sliding them apart. Keep them away from bank cards, sensitive electronics and medical devices.
