摘　　要：在普通物理的教学中引入矢量势的概念可帮助学生对静电场和静磁场的对比理解,同时借助于简单的矢量运算规则还能对偶极辐射是电磁辐射的基本构成这一概念给出数学解释,加深理解,有助于后续课程的学习和衔接.The introduction of the concept of vector potential in the teaching of general physics can help students deepen their understanding of electrostatic field and static magnetic field on the basis of comparative comparison.At the same time,with the help of simple vector operation rules,it can also show mathematical explanations for the dipole radiation as the basic composition of electromagnetic radiation.Such understanding about vector potential and dipole radiation will be helpful for the learning and articulation of subsequent courses.
