Neodymium Rod Magnet 3 x 8 mm N48
 
Neodymium (NdFeB) is among the strongest magnetic materials and provides substantial holding force for its size. Compared with ferrite, neodymium provides much greater magnetic attraction. The magnet generally has a protective surface coating. N48 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52. The cylinder magnet can be incorporated discreetly into components, holders or housings and is easy to align.
 
This size suits compact applications, including small attachments and simple assemblies on flat metal surfaces. (Ø3×8 mm) Paint, film or gaps noticeably reduce magnetic attraction. The magnet performs best on a flat, clean surface.
 
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.
