摘要
根据方形线圈的磁场分布公式,通过数值计算,得到了两个长度为2l、相互距离为d的同轴等大方形线圈的互感磁通量与电流、长度和相互距离之间的数值关系,并利用绘图软件Origin7.5强大的线性回归和曲线拟合功能,给出了两个同轴等大方形线圈的互感系数的近似解析式.计算结果表明,互感系数由方形线圈的长度和相互距离决定,而与电流无关.
Relation of magnetic flux,current ,length and distance between two square loops with the same axis and size is got through the numeral calculation according to the formula of magnetic field, then the approximate analytic formula of mutual- inductance is obtained by using Origin7.5 which has powerful function of linear regression and curve simulating. The result of calculation indicates that mutual - inductance is determined by the length and distance of two square loops, and is independent of current.
