Ferrite e na le matla a matla a khoheli le tahlehelo e tlase ea hysteresis; pearlite e fapane feela, e na le matla a fokolang a matla a khoheli le tahlehelo e kholo ea hysteresis. Pearlite e entsoe ka ferrite ka kalafo ea mocheso e anneal, e ka eketsang matla a khoheli ka makhetlo a mane. Ho eketsa lijo-thollo tsa ferrite ho ka fokotsa tahlehelo ea hysteresis. Ho ba teng ha cementite ho tla fokotsa matla a khoheli a matla a khoheli, permeability le remanence, ha a ntse a eketsa ho felloa ke matla le tahlehelo ea hysteresis. Ho ba teng ha graphite e mahoashe ho tla fokotsa ho sala morao.
