摘　　要：针对电磁学教学中安培定律数学形式复杂、物理涵义难以理解的特点,该文提出将其与库仑定律进行对比。通过对物理涵义、理想模型、公式形式、作用力性质及传递媒介以及理论地位等多个方面的类比,找出二者的联系与区别,从而帮助学生建立起新旧知识之间的联系,加深对安培定律的理解以及电磁规律对称性的认识,进而有效提高课堂教学的质量及效率。Considering the characteristics of the complicated mathematical form and incomprehensible physical connotation of Ampere’s law,this paper proposes to compare it with Coulomb’s law.Through the analogy of physical meaning,physical model,formula form,force nature and transmission medium,and theorem derivation,the connection and difference between the two laws could be found out,so as to help students establish the connection between new and old knowledge and deepen the understanding of Ampere’s law and the symmetry of electromagnetic law,which might effectively improve the quality and efficiency of teaching.
