直螺线管对称轴上的磁场

The Magnetic Field on the Axis of symmetry of vertical Solenoid

文章以矩形螺线管轴线上的磁场分布特点为基础 ,将螺线管的对称截面按矩形进行分割 ,分析得出螺线管对称轴上磁场分布的一般规律。

On the basis of the distributive features of magnetic field on the axis of the rectangular solenoid,and by separating symmetric section of solenoid into rectangles,we can find the general regularity of the distributing of the axis of symmetry of solenoid and can also come to the conclusion that the distribution of the magnetic field on the axis of symmetry of solenoid has nothing to do with the shape of its cross section which is proved by some concrete examples.
