摘要
通过保角变换得出椭圆形电流的磁场在变换空间分布的柱坐标表示 .对椭圆形电流的磁场在空间中极端位置的直角坐标表示进行了求解 ,求解的结果表明在椭圆退化为圆 (即a=b)的情况下 ,能与传统方法得到的圆形电流的磁场在轴线上和圆心上的值自洽 。
A space distribution of cylinder coordiuate of an ellipse current magnetic field is derived by conformatransformation,we have calculated the value of right angle coordinate about a ellipse current magnetic field in the extrem position.The result accord with the value calculated by the means of tradition way,while the ellipse change into the circle(a=b)on the axes and the centre of circle,and the limit value of magnetic on the area of outer circle in infinite position is derived.
