NdFeB Magnets / Neodymium Iron Boron Magnets Datasheet

NdFeB magnets are sintered anisotropic materials - they have a preferred direction of magnetisation locked into their structure. So the magnet can only be magnetised in one axis - any attempt to magnetise in another axis results in very little performance. Each NdFeB magnet has a Direction of Magnetisation (DoM). In drawings the poles are labelled (with a North or a South) or the magnet shape ...

About magnetism | Goudsmit Magnetics

Of all magnetic materials, ferromagnetic materials are the only materials that are strong enough to be attracted by a magnet or to be used as magnet material. Ferromagnetic materials can be divided into magnetically soft materials, such as annealed iron, which can be magnetized but do not retain the magnetization, and magnetically hard materials that do remain magnetized. Back to top ...
