Neodymium Disc Magnet 40 x 12 mm N50
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. The N50 magnet belongs to the NdFeB family, commonly ranging from N35 to N52; a higher number generally means greater magnetic attraction.
The larger size suits more demanding tasks, including strong attachments, handling, assembly and robust projects, also in industrial environments. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
Warning: keep away from children. Two magnets can snap together quickly, pinch fingers and crack or chip. Use spacers for storage and take care when separating them. Keep them away from medical devices and objects sensitive to magnetic fields, including cards and electronics.
