摘要
针对电磁场教学的难点 ,通过形象化的场图等辅助手段帮助学生理解和掌握电磁场的规律。介绍了科学计算语言 MATL AB的特点及其在辅助教学中的应用 ,详述了 MATLAB在电磁场教学中的一些具体应用实例 ,包括利用可视化功能进行场图绘制、三维图形交互 ,运用符号运算功能进行数学公式推导 ,根据数值计算功能进行习题求解等。最后还介绍了利用 MATL AB的 PDE工具箱给学生有限元法的初步认识。
Aiming to difficulties in electromagnetic field teaching, aided means such as imaging pictures of electromagnetic field etc. are used to help students comprehend and grasp laws in electromagnetic field. Features of scientific computing language MATLAB and its applications in aided instruction are introduced. A few examples used in electromagnetic field teaching are explained in detail. They include field figure drawing and 3D figure interaction by visualization function, formula deduction by symbolic operation function, exercises computing by numerical calculation function, etc. In the end, use of PDE tool in MATLAB to give students elementary understanding of finite element method is introduced.
