Neodymium Ring Magnet 8 x 5 x 5 mm N48
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. Alongside high magnetic attraction, the surface coating helps improve durability. N48 indicates the magnetic grade, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. The central hole simplifies mounting and positioning, making it useful for frames, holders and repeatable installations.
This size suits compact applications, including small attachments and simple assemblies on flat metal surfaces. (Ø8/Ø5×5 mm) Paint, film or gaps noticeably reduce magnetic attraction. The magnet performs best on a flat, clean surface.
Warning: not suitable for children. Swallowed magnets can cause serious injuries. Seek urgent 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.
