The rare earth Neodymium magnet is regarded as the strongest kind of permanent magnet available in the world at present. In this article, we would like to provide some information about how they are manufactured and their applications.
Neodymium Magnets are a particular category of earth magnets, this rare earth magnet is the strongest kind of permanent magnet available in the world at present. These magnets are now manufactured commercially for their potential in storing high amounts of magnetic energy as well as energy density. General Motors first commercialized this neodymium magnet to use as an alternative for other types of permanent magnets which were much higher in cost. The magnets one disadvantage of deteriorating too easily was eliminated with the use of nickel plating which then became the standard in the production of neodymium.

We mainly produced sintered NdFeB because it is the one widely used in many fields. The coercive force of Sintered NdFeB is very high and its Bhmax is about ten
times of that of Ferrite magnet. As its fairly good mechanical properties, it can be processed into many different shapes or with various holes. Some of its products
with high-performance can work under the situation up to 200℃. However, it is easy to be rusted for its elements. Therefore we should make surface treatment in
accord with different requirements, such as zinc-coated, Nickel-coated, Ag- coated, Au-coated,Epoxy-coated etc.
