Neodymium Disc Magnet 6 x 1 mm N48
 
A neodymium magnet (NdFeB) is small but very strong. It is made from a special alloy and magnetised in a strong magnetic field during manufacture. Compared with conventional ferrite magnets, neodymium provides much greater magnetic attraction. A protective coating helps improve durability. N48 indicates the magnetic grade; a higher number generally means a stronger magnet, with grades commonly ranging from N35 to N52.
 
The small size suits precision tasks such as model making, prototypes, electronic components and very discreet attachments. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
 
Warning: not suitable for children. Strong magnets can snap together suddenly, causing pinching injuries, and may break. Bring them together and separate them carefully. Keep them away from medical devices and objects sensitive to magnetic fields, including cards and electronics.
