【摘要】 在电磁学教学中，学生对理解电场和磁场分布的相关问题存在困难。文章运用Mathematica软件对电磁学教学中半圆环和直导线典型问题进行可视化操作，将课堂中手工推算的内容转化为直观的图像，有利于学生对电磁学的学习，锻炼学生的逻辑思维、分析问题、解决问题的能力，并增强其创新能力。为验证其教学效果，文章运用SPSS软件对实验组和对照组大学物理成绩进行差异性分析。更多还原

【Abstract】 To address the difficulties in understanding the distribution of electric and magnetic fields in electromagnetic teaching, Mathematica software can be used for visual analysis and understanding. In this article, Mathe-matica software is used to visualize typical problems of semicircular rings and straight wires in electromagnetic teaching, transforming the original manual calculation content in the classroom into intuitive images. This is beneficial for electromagnetic learning of students, cultivating their logical thinking, analytical and problem-solving ability, enhancing their innovation capability. At the same time, SPSS software was used to analyze the differences in the scores of College Physics between the students in control group anol experimental group.更多还原
