摘要
根据一对反平行无限长载流直导线周围等磁矢势线的特点,与分离载流薄圆筒表面的等磁矢势线进行类比,采用等效替代法方便地得到分离载流薄圆筒周围的等磁矢势线函数与磁场强度函数.
The magnetic vector potential line between a pair of current straight wire and current-carrying thin cylinders is compared according to the characteristics of magnetic vector potential line.The function of the magnetic vector potential about current-carrying thin cylinders is easily calculated.
