摘要
根据电磁感应定律和螺线管电流磁场的特点,建立长直螺线管内部和表面的磁场的有限元模型.依据比奥-萨法尔定律和安培环路定理,对长直螺线管磁场进行理论分析和数学推导,得到其磁场分布的特点及其解析解.利用Ansoft Maxwell 3D工程电磁场有限元软件对其进行仿真,验证了结果的一致性及利用ANSYS软件进行电磁场分析的直观性和便利性.
According to the law of electromagnetic induction and the characteristics of current magnetic field of solenoid, a finite element model of the magnetic field on the surface or the interior of long straight solenoid was established. By means of theoretical deduction and numerical analysis based on the law of biot savart and Ampere circuital theorem of magnetic field in a straight solenoid, the characteristics of dis- tribution of magnetic field and its analytical solution were obtained. The simulation was carried out on using of Ansoft Maxwell 3D engineering electromagnetic field finite element software, the consistency of the result and the intuitive and convenient of using ANSYS software for electromagnetic field analysis were verified.
