We analyze the EI-shaped iron-core inductors with air-gaps by using 2-D finite element analysis considering vector magnetic property. We can investigate the iron loss distribution in the cores affected by the length of the air-gaps. As a result, we can show the difference of local iron loss distribution in the inductor cores when the length of the air-gaps is changed. Moreover, it is shown that the iron loss distribution differs from the maximum flux density distribution. Streszczenie. Przeanalizowano rdzen typu EI metopdą elementu skonczonego z uwzglednieniem wlaściwości wektorowych. Zbadano wplyw wielkości szczeliny. Stwierdzono rozny rozklad lokalnej wartości strat zalezny od wielkości szczeliny. Ten rozklad styrat zalezy tez od wielkości indukcji.
