permanent magnets available today, with maximum energy product ranging from
35 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed
in the 1980s. It has a combination of very high remanence and coercivity, and comes with
a wide range of grades, sizes and shapes. With its excellent magnetic characteristics,
abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of
new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve
high efficiency, low cost and more compact devices.
