Neodymium Disc Magnet 10 x 1.5 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. Neodymium is much stronger than ferrite, and its protective coating helps prevent corrosion. N48 indicates the magnetic grade; NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets.
 
At Ø10 × 1.5 mm, this magnet provides a good hold on metal and is useful at home, in workshops and for a variety of projects. Even a small gap caused by thick paint, tape or an uneven surface noticeably reduces holding force. It performs best on solid steel.
 
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.
