用数值模拟方法,分析计算了疏松型椭圆截面螺线管电流的磁场与螺距、长宽比、管内位置的关系。计算结果表明,当螺距较大时,其磁场分布与密绕螺线管电流的磁场分布相差很大,磁场在空间各个方向都有分量,螺距越大,螺线管越短,垂直于螺线管轴线方向的磁场分量越强;但当螺距较小、螺线管越短较强时,其磁场与密绕螺线管电流产生的磁场基本相同,可用密绕螺线管电流的磁场近似。
By numerical simulation, the relationship between the magnetic field and pitch, aspect ratio and position in the tube of the loosening elliptical section solenoid was analyzed and calculated. The calculation results show that when the pitch is large, the magnetic field distribution is quite different from that of the close-wound solenoid current. The magnetic field has components in all directions of space. The larger the pitch is, the shorter the solenoid is and the perpendicular to the spiral However, when the pitch is small and the solenoid is shorter and stronger, the magnetic field generated by the magnetic field is similar to the magnetic field generated by the close-wound solenoid current, and the magnetic field close to the solenoid current can be approximated.
