If you want to ask how to deal with rising price of rare earth, GBD process NdFeB magnet is a good solution for high-end neodymium magnets. As already discussed in previous sections, the NdFeB magnet has various grades:- each grade has its own magnetic properties (relating to strength of magnetic field output and resistance to demagnetization, maximum recommended operating temperature and temperature coefficients). The excellent magnetic properties of VACODYM are traced to the strongly magnetic matrix phase Nd 2 Fe 14 B with very high saturation polarization and high magnetic anisotropy. Neodymium is a metal which is ferromagnetic (more specifically it shows antiferromagnetic properties), meaning that like iron it can be magnetized to become a magnet, but its Curie temperature (the temperature above which its ferromagnetism disappears) is 19 K (−254.2 °C; −425.5 °F), so in pure form its magnetism only appears at extremely low temperatures.
