摘要
根据圆电流在远处产生的磁场与磁偶极子产生的磁场等效,证明无限长密绕螺线管外一点的轴向磁场可视为零。
Because the magnetic field, which is produced by circular electric current in the long distahee, is equal to the magnetic field produced by magnetic dipole, we can prove thet the axial magnetic field B of a outside point of the infinitely long high-density solenoid is zero.
