基于MATLAB的载流圆环磁场分布的动态仿真

摘要

According to Biot-Savart Law,the integral representation of the magnetic field distribution of a cur-rent-carrying coil is derived.The computed results are given by using with MATLAB and the simulations of the vector graphy of magnetic field distribution,the graphs of magnetic field distribution on the central axis,in the surface which is parallel to the coli and the surface which is vertical to the coli are carried out. The three-di-mensional distribution of the magnetic filed in the radial and axial direction is studied,which plays a guiding role in education and application of practical engineering.%根据毕奥—萨伐尔定律推导出载流圆环空间磁场分布的积分表达式，利用MATLAB给出计算结果，并对磁场分布矢量图、中心轴线上磁场分布图、与圆环面平行及垂直的面上磁场分布图进行仿真，研究了磁场在径向和轴向的三维分布，对教学和实际工程应用具有一定的指导作用。
