摘　　要：由对作用在磁荷上磁性力的定性分析得悉,圆形平面内均匀分布的有限个磁荷在库仑斥力的相互作用下,一部分沉积到了圆棱线上,形成沿圆棱线的线磁荷,其余的则只能被遗留在圆平面内。对19个和20个磁荷系统的数值计算验证了上述结论,前者中的12个磁荷均布于圆棱线上,一个居圆心,6个均布于圆内且距圆棱线0.37R(R为圆半径);后者中有18个磁荷沿圆棱线,2个在圆内且距圆棱线0.70R。It is known from the qualitative analysis for the magnetic force acting upon a magnetic charge that a part of the finite magnetic charges uniformly distributing in a round plane deposits upon the circular edge under the interaction of Coulomb＇s repulsion to form a linear magnetic charge along the circular edge, and the rest can only be left in the round plane. This conclusion mentioned above is verified by the numerical calculation for the system of 19 and 20 magnetic charges： in the former 12 magnetic charges distribute uniformly along the circular edge, one stay on the centre of circle, and six distribute uniformly in the round from the circular edge 0. 37R（R is the round radius） ; and in the later there are 18 magnetic charges along the circular edge and two magnetic charges in the round from the circular edge 0. 70 R.
