摘　　要：在电磁学课程中,各种矢量场的抽象性以及数学描述的复杂性,使得电磁场空间分布的正确理解成为教学过程中的难点和重点内容。本文以Matlab语言为例,利用该语言在科学计算及可视化方面的优势,针对静电场场强、电势的空间分布、磁场的空间分布等案例进行了建模、数值计算、可视化显示及分析,系统展示了仿真计算和可视化对电磁学课程教学的辅助功能。基于近几年来的课程教学实践发现,通过引导学生将科学计算和仿真应用于电磁学相关问题的求解和分析,对提高学生的数学建模能力和数值计算能力具有重要提升作用,促进计算机、数学和电磁学的交叉学习,提升课程的深度和广度。相对于单纯的电磁学讲授,增加电磁学相关问题的计算机编程、仿真和分析能显著提高学生的课程获得感。In the course of electromagnetism,the abstractness of various vector fields and the complexity of mathematical descriptions make the correct understanding of the spatial distribution of electromagnetic fields a difficult content in the teaching process.Taking the advantages of the Matlab in scientific calculation and visualization,the modelling,numerical calculation,visually display and analysis of spatial distributions of electrostatic field,potential and magnetic field are demonstrated in this paper,it displays the important role played by the simulation and visualization in the teaching of electromagnetism.Based on the teaching practice of the course in recent years,it has been found that by guiding students to apply scientific computing and simulation to the solution and analysis of problems related to electromagnetism,it plays an important role in improving studentsmathematical modeling and numerical calculation abilities.It promotes the interdisciplinary learning of computer science,mathematics,and electromagnetism,enhancing the depth and breadth of the course.Compared to the conventional way in teaching electromagnetism,adding computer programming,simulation,and analysis of electromagnetic problems can significantly improve studentssense of course acquisition.
