A phenomenon of mutual influence of the demagnetizing field and a gradual increase of width of minor loops in bulk ferromagnets during magnetization processes is scrutinized by computational modeling. Classical static micromagnetics is here enriched by a suitable activated dissipation mechanism allowing for rate-independent hysteresis.

Pocitacově modelujeme vliv demagnetizačního pole na minoritní hysterezní smyčky. Klasický mikromagnetismus je v modelu doplneň disipačním mechanismem, který nezavisí na rychlosti magnetizace
