Neodymium Block Magnet 50 x 25 x 12.5 mm N35
 
A neodymium magnet (NdFeB) is a very strong magnet magnetised in a strong magnetic field during manufacture, providing high magnetic attraction in a compact 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.
 
This block magnet is intended for demanding tasks requiring very strong attachment and industrial use. Handle it with extra care. 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 medical devices and objects sensitive to magnetic fields, including cards and electronics.
