Neodymium Ring Magnet 18 x 5.2 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 central hole simplifies mounting and positioning, making it useful for frames, holders and repeatable installations.
A good choice where stronger holding force is needed and a ring that fits over a shaft or screw is useful. (Ø18/Ø5.2×3 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 medical devices, cards and sensitive electronics.
