| 摘 要： | 在求解域内存在磁性介质的静磁场问题时,将磁性介质视为二次场源是方便的。从静磁场基本问题出发可以导出作为二次场源的磁性介质的两种等效模型,即束缚电流模型和等效磁荷模型。并分别给出了由这两种模型导出的求解磁性介质内部磁化强度分布的积分方程。最后还给出了由等效磁荷模型导出的积分方程数值求解的数学模型。

| Abstract: | It is convenient to consider the magnetic medium as a secondary field source in solving the magnetostatic problems. There are two kinds of equivalent models for magnetic medium considered as a secondary field source (the fettered current model and the equivalent magnetic monopole model) which can be deduced from the basic equations of magnetostatic field Two integral equations for solving the magnetization distribution in magnetic medium which separately come from these two kinds of models are given in this paper. Finally in order to numerically solve the above integral equation a mathematical model (a group of algebraical equations) is also given. |
