Neodymium Disc Magnet 60 x 10 mm N35
 
A neodymium magnet (NdFeB) is a very strong magnet produced by aligning the alloy particles in a strong magnetic field during manufacture. 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.
 
The larger design suits demanding applications, including attachments with high magnetic attraction, grippers and professional projects. 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 sensitive electronics, cards and medical devices.
