Neodymium Disc Magnet 18 x 3 mm N35
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. N35 indicates the magnetic grade; a higher number generally means a stronger magnet, with grades commonly ranging from N35 to N52.
At Ø18 × 3 mm, this magnet provides a strong hold for quick assemblies, tools, DIY and general applications on steel. 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: not suitable for children. Strong magnets can snap together suddenly, causing pinching injuries, and may break. Bring them together and separate them carefully. Keep them away from sensitive electronics, cards and medical devices.
