Khan Academy India explains these properties using hysteresis graphs to illustrate retentivity and coercivity. Ferromagnets with high retentivity and coercivity are used as permanent magnets (hard magnets), while the ones with low retentivity & coercivity (soft magnets) are used as cores in electromagnets. But all ferromagnets have high permeability.
