Neodymium Block Magnet 40 x 30 x 15 mm N35
 
An NdFeB (neodymium) magnet provides high magnetic attraction for its size, making it useful for technical projects, DIY and industrial applications. Compared with ferrite, neodymium provides much greater magnetic attraction. A protective surface coating helps improve durability. N35 indicates the magnetic grade. NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets. The rectangular block shape is practical for assembly. It is easy to align, provides a good contact surface and fits well into fixtures and grooves.
 
This block magnet is intended for demanding tasks requiring very strong attachment and industrial use. Handle it with extra care. 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.
