A number of sample applications are discussed in which
the change to NdFeB has already been made. One reason
for the use of NdFeB is the material's good magnetic
values at room temperature. They are of benefit above
all in magneto mechanics, since the forces and torques
are proportional to the square of remanence B . One weak
point of the new material is its low resistance to corrosion and radiation, which necessitates protective measures. Of much greater significance, however, is the
sharp drop in coercivity H  which occurs with increasing temperature.
