摘　　要：利用通电线段的磁感应强度公式,建立了二维平面中的矢量式,推导了在三维直角坐标系中的矢量式,最后形成了任意平面多边形载流线圈的磁感应强度的简要公式。将公式无量纲化,利用MATLAB指令,绘制了矢量图,三维磁感应线,磁感应强度各分量和合场强的曲面图,以及切片图,显示了磁场在空间的分布规律。In this paper, by using the magnetic induction intensity formula of the power line segment, the vector formula in the two-dimensional plane is established, and the vector formula in the three-dimensional rectangular coordinate system is deduced, therefore, a brief formula of the magnetic induction intensity of an arbitrary plane polygonal current-carrying coil is formed. The formulas are dimensionlesslized. Meanwhile, by using MATLAB commands, the vector diagrams, the three-dimensional magnetic induction lines, the surface diagrams of the components of magnetic induction, the combined field strength, and the slice diagrams are drawn, so as to show the distribution of magnetic fields in space.
