WebIn the case of soft magnetic materials, we require as small as possible coercivity because hysteresis power loss strongly depends on this value Conversely, in the case of hard magnetic materials, we need to have as large as possible coercivity and remanence because stored magnetic energy approximately depends on the H c ·B r value (Figure 3.62). WebSoft magnetic materials are characterized by low values of coercivity (H c <10 3 A m –1), while the coercivity of hard magnetic materials (usually permanent magnets) is higher than 10 4 A m –1. Finally, semihard magnetic materials (mostly storage media) have coercivities in between the above two values.

WebOct 26, 2024 · Abstract. Soft magnetic materials are key to the efficient operation of the next generation of power electronics and electrical machines (motors and generators). Many new materials have been introduced since Michael Faraday’s discovery of magnetic induction, when iron was the only option. WebIn soft iron, the domains return to being randomly aligned when the field is removed. Hard iron is used in permanent magnets. To make a permanent magnet, a piece of hard iron is placed in a magnetic field. The domains align with the field, and retain a good deal of that alignment when the field is removed, resulting in a magnet. An ...
