The neodymium atom also can have a large magnetic dipole moment because it has 7 unpaired electrons in its electron structure as opposed to (on average) 3 in iron. In a magnet it is the unpaired electrons, aligned so they spin in the same direction, which generate the magnetic field. This gives the Nd2Fe14B compound a high saturation magnetization (Js ~1.6 T or 16 kG) and typically 1.3 teslas. Therefore, as the maximum energy density is proportional to Js2, this magnetic phase has the potential for storing large amounts of magnetic energy (BHmax ~ 512 kJ/m3 or 64 MG·Oe). This magnetic energy value is about 18 times greater than “ordinary” magnets by volume. This property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed.
All the Ring Countersunk NdFeB Magnet types can be used for ambient temperature indoor applications where moisture content is low or negligible. NdFeB Pot Magnets are best for maximum pull strength with a small size. Ferrite Pot Magnets can be used for corrosion resistance, marine, low cost and higher temperature applications. Alnico Pot Magnets can be used in higher temperature applications and where the pull force needs to change as little as possible with temperature variation. Alnico Pot Magnets can also be used in corrosion resistance applications. SmCo Pot Magnets can be used for extreme temperature applications and marine / corrosion resistance applications.
