| 摘 要： | 从表征磁场特性的场函数出发,推导出通电圆形线圈平面径向各点的磁场强度值的计算公式,进而推论到整个线圈平面及与线圈平面平行而距离为不同值的任一平面内的任一点的磁场强度值的计算公式,从而可以求得通电线圈在其附近整个空间的磁场强度值的分布情况,这就弥补了只能在特定的线圈中心点计算出磁场强度值的不足,用计算机进行数字仿真即可定量的获得磁场强度在空间的分布情况.

| Abstract: | The formula to calculate value of magnetic strength close by the current circle is deduced from the magnetic characteristic field function.Other formulas that calculate arbitrary point of magnetic strength value through plane the current circle are given and the plane parallel to the plane in the current circle is deduced further.Consequently,the paper has concluded distribution of magnetic strength value close by the current circle.The conclusion will cover the shortage that magnetic strength value is computed only in the center of the current circle.Distribution of magnetic strength value is obtained by the technology of computer digital emulation. |
