2. Magnet Display
Neodymium-Iron-Boron (NdFeB) magnets are composed of neodymium, iron, boron and a few transition metals. These kind of permanent magnets are extremely strong and can be producted in different shapes and sizes (ie. arcs, blocks, discs, rings).
It has higher unit magnetic properties than other magnet and assure you of smaller size and lighter weight in designing devices.
