Neodymium Disc Magnet 8 x 2 mm N48
 
A neodymium magnet (NdFeB) is a very strong magnet produced by aligning the alloy particles in a strong magnetic field during manufacture. Compared with conventional ferrite magnets, neodymium provides much greater magnetic attraction. A protective coating helps improve durability. The N48 magnet belongs to the NdFeB family, commonly ranging from N35 to N52; a higher number generally means greater magnetic attraction.
 
At Ø8 × 2 mm, this magnet provides a good hold on metal and is useful at home, in workshops and for a variety of projects. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
 
Warning: keep away from children. Strong attraction can cause pinching injuries, and the magnet can chip easily. Store magnets with spacers and avoid impacts. Keep them away from sensitive electronics, cards and medical devices.
