Neodymium Block Magnet with Countersunk Hole 50 x 10 x 5 mm N48.
An NdFeB (neodymium) magnet provides high magnetic attraction for its size, making it useful for technical projects and practical attachments. Compared with ferrite, neodymium provides much greater magnetic attraction. A protective surface coating helps improve durability. N48 indicates the magnetic grade; NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. This magnet with a Mounting Hole for easy installation in a frame, holder or panel.
The 50×10×5 mm size provides a strong hold for practical tasks, including quick assemblies, attachments and technical projects. Holding force depends strongly on the thickness and condition of the metal surface. It is greater on thick steel than on thin sheet metal. Use moderate tightening force, avoid overtightening and use a washer where possible. Impacts or excessive clamping pressure can crack the magnet.
Warning: not suitable for children. Two magnets can snap together quickly, pinch fingers and crack or chip. Separate them carefully and avoid impacts. Keep them away from bank cards, sensitive electronics and medical devices.
