摘要
应用新物理模型——螺旋形面电流,根据磁场的边界条件,边值关系,分析讨论了长直载流螺线管激发的磁场分布,得到其磁感应强度为={μ0nIez(r<R),μ02πrIeθ(r>R).
Abstract： This paper applies the new physical model： the spiral surface current. Based on the boundary conditions of magnetic field and the value relations, it analyzes and proves the magnetic field distribution which straight the long straight solenoid stimulates, the magnetic induction intensity isB={μ0nI-ez（r〈R）μ0iIA/2πe-θ（r〉R）.
