用切片法求轴对称载流导体的磁感应强度

The intensity of magnetic of long straight current-carrying conductor at symmetrical

摘要: 将正方形截面长直载流导体沿电流方向分割成许多薄片 ,积分求出了对称轴上的磁感应强度 ,并讨论了截面中心附近和远离导体处磁感应强度的近似计算方法

Abstract: The long straight current carrying conductor with a square section being cut into many flake along the direction of the current,and the intensity of magnetic induction at symmetrical axes is calculated.The approximate calculation of intensity of magnetic induction either near the center or far away from the center are discussed.
