Neodymium Disc Magnet 10 x 10 mm N48
 
A neodymium magnet (NdFeB) is a very strong magnet produced by aligning the alloy particles in a strong magnetic field during manufacture. It is noticeably stronger than conventional ferrite magnets and generally has a protective coating because the material is prone to corrosion. The N48 magnet belongs to the NdFeB family, commonly ranging from N35 to N52; a higher number generally means greater magnetic attraction.
 
At Ø10 × 10 mm, this magnet provides a strong hold for quick assemblies, tools, DIY and general applications on steel. Even a small gap caused by thick paint, tape or an uneven surface noticeably reduces holding force. It performs best on solid steel.
 
Warning: keep away from children. Strong attraction can cause pinching injuries, and the magnet can chip easily. Store magnets with spacers and avoid impacts. Keep them away from bank cards, hard drives, sensitive electronics and medical devices.
