摘要: 在柱坐标系中,直接从磁感应强度的计算公式毕奥-萨伐尔定律出发,在更为普遍的情况下得到了圆电流空间磁场的一般分布,并绘制出磁场的空间分布图,讨论了圆电流平面上、中心轴线以及远区的磁场.

关键词: 圆电流, 磁场分布, 椭圆积分

Abstract: The general expression of the magnetic field at the arbitrary point of a current loop is presented by using Bio-Savart's law directly and the spatial distribution diagrams of the magnetic field strength is drown by using computers. The magnetic field strength at the center axis of the loop, on the plane of the current loop and in the distant area are discussed in detail too.

Key words: current loop, magnetic field
