摘要
首先证明了正Ｎ边形截面长直螺线管内部磁感应强度的公式，进而证明了长直螺线管内部磁感应强度与横截面的形状无关。
In the first place, a formula is proved for indicating a magnetic induction strength inside a long straight helix tube carrying current, with the tubes cross section in tetragonal N regular polygon. Accordinglly, no relationship is proved, either, between the magnetic induction strength inside this long straight helix tabe carrying current and the shape of the cross section.
