| Abstract: | 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. |

| Keywords: | magnetic induction magnetic moment coefficient of mutual induction coefficient of self-induction tension |
