Neodymium Block Magnet 7.5 x 5 x 15 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. The magnet magnetised along the length: the poles are on the end faces, so the field direction differs from a conventional block magnet and suits some applications better.
The 7.5×5×15 mm block is suitable where a substantial but manageable hold is needed in workshops. Even a small gap caused by paint, tape or clearance noticeably reduces magnetic attraction. It performs best on solid steel.
Warning: keep out of reach of children. Magnets can snap together suddenly, pinch skin and chip or break on impact. Handle them carefully when bringing them together or separating them. Keep them away from bank cards, sensitive electronics and medical devices.
