摘要
从毕奥—沙伐尔公式出发,导出圆电流磁场的一般表达式。用以计算磁矩的某些特殊区域的磁场和共轴周线圈的互感以及圆线圈的外自感和载流圆线圈中自磁场引起的张力。
According to Biot-Savart law,a gneral formula on magnetic field of circular current is deduced.With this formula,the field of magnetic moment in some special region,the coefficient of mutual induction of two coaxal circular coils,the coefficient of self-induction of circular coil,and the tension which is caused by self-magnetic field of the circular current can be calculated.
