... as the saturation induction. When the magnetizing field is reduced to zero in permanent magnets, most of the induction is retained. In Fig. 1 , when the field is reduced through zero and reversed to −S, the induction decreases from +S to B r to −S. At zero field, there is a remanent magnetization in the sample...
