Neodymium Iron Boron 5x3mm N35H Disc Magnet

5 x 3mm permanent disc magnet made from N35H grade sintered Neodymium Iron Boron (NdFeB). This type of magnet material gives the highest energy per unit volume of any permanent magnet material, being capable of lifting up to 1000 times its own weight. Suitable applications for this disc magnet include audio and renewable energy. Good strength to 120°C Remanence recoverable on falling temperature. Magnetic losses over time and from vibration are minimal.
