摘　　要：以一片变压器的铁心叠片即薄平板导体为模型,用有限元方法直观地表现因涡流效应而引起的磁场与电流的变化,并分析影响涡流大小的因素和减小涡流损害的方法。A thin flat conductor in a transformer is used as a model, the change of magnetic field and electric current caused by eddy current effect is directly analysed by finite element method. And the factors influencing the intensity of eddy current effect are given, as well as the methods to reduce its bad affects.

关 键 词：涡流效应 磁场 有限元法
