摘要
闭合线圈在磁场中运动,线圈中的电流变化将产生自感,自感电流对总感应电流的贡献是不容忽视的。利用磁矢势求出闭合圆线圈的自感系数,进而计算出闭合圆线圈在均匀磁场中旋转时产生的自感电流和总感应电流,结果表明在某些条件下自感因素的影响很大。
The current intensity of variations will produce self-induction when a closed coil moves in magnetic field. Must be attended to the contribution of the current by self-induction to total current. First, calculate the self-induction coefficient of closed coil on the basis of the vecto magnetomotive potential. And then, the total current and the current by self-induction of closed coil when it turns in magnetic field are counted. The result shows that the effect of self-induction is very strong.
