Neodymium Block Magnet 15 x 6 x 2.8 mm N35
 
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. A protective surface coating helps improve durability. 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 15×6×2.8 mm size provides a strong hold for practical tasks, including quick assemblies, attachments and technical projects. For good results, use a flat, clean metal surface. Any gap caused by thick paint or an uneven surface reduces holding force.
 
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.
