摘要
由面电流在空间某点的磁场公式出发,利用场强叠加原理,计算出截面为任意多边形的无限长载流柱面在空间任意点的磁场分布,并且运用这种方法求出了截面为菱形的无限长载流柱面空间磁场分布的普遍表达式.
According to the magnetic field formula of surface electric current and superposition principle of field intensity,that was introduced a method to calculate the spatial distribution of magnetic field generated by infinite cylinder electric current with polygonal cross section.Then the general expression of magnetic field generated by infinite cylinder electric current with rhombic cross section is derived by using this method.
