基于Mathematica的电磁场散度和旋度分布仿真实验研究

Research on Simulation Experiments of Field Distribution of Divergence and Curl in Electromagnetic Field based on Mathematica

散度、旋度是研究电磁场理论的基础,由于其定义抽象难以理解,不利于后续内容的学习。该文在实验教学中利用Mathematica对各种矢量场散度、旋度空间分布进行仿真,可以方便地画出矢量场的分布图,让学生直观地看到发散场、旋涡场的分布特点,更好地理解散度、旋度以及亥姆霍兹定理的意义。

Divergence and curl are the basis of the research on electromagnetic field theory. For abstract define, divergence andcurl affect the follow-up content of learning. The software Mathematica is introduced for the experimental teaching of divergenceand curl in electromagnetic field, which can easily draw the vector field distribution. Therefore, these help the students to see diver-gence field and vortex field distribution characteristics visually and better understand the meaning of divergence and curl andHelmholtz＇s theorem.
