Neodymium Block Magnet 20 x 8 x 8 mm N35
Neodymium (NdFeB) is among the strongest magnetic materials and provides substantial holding force for its size. Its magnetic attraction is greater than that of ferrite magnets, and the surface coating helps reduce corrosion. N35 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. The rectangular shape is useful for frames, edges and applications requiring an elongated, stable magnet.
The 20×8×8 mm size provides a strong hold for practical tasks, including quick assemblies, attachments and technical projects. Even a small gap caused by paint, tape or clearance noticeably reduces magnetic attraction. It performs best on solid steel.
Warning: keep out of reach of children. Magnets can snap together suddenly, pinch skin and chip or break on impact. Handle them carefully when bringing them together or separating them. Keep them away from bank cards, sensitive electronics and medical devices.
