Description
Chapter 4 summarizes selected applications and the production aspects of
hard magnets. Hard magnets (= permanent magnets with large coercive
field and high remanence magnetization) are used in applications for which a large induction B
is needed without an applied field H. The figure of merits of hard
magnets, i.e., the max. energy product (BH)max, is introduced and its
significance
