Neodymium Ring Magnet 20 x 9.4 x 5 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, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. 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.
At Ø20/Ø9.4×5 mm, this magnet provides a strong hold for workshop use, assembly, alignment and technical projects. (Ø20/Ø9.4×5 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 bank cards, sensitive electronics and medical devices such as pacemakers.
