Neodymium Disc Magnet 18 x 15 mm N48
An NdFeB (neodymium) magnet provides high magnetic attraction for its size, making it useful for technical projects, DIY and quick attachments. Neodymium is much stronger than ferrite, and its protective coating helps prevent corrosion. N48 indicates the magnetic grade; a higher number generally means a stronger magnet, with NdFeB grades commonly ranging from N35 to N52.
The larger design suits demanding applications, including attachments with high magnetic attraction, grippers and professional projects. The actual hold depends on the contact surface and the thickness of the metal. Holding force is greater on thick steel than on thin sheet metal.
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, sensitive electronics and medical devices.
