摘　　要：由于电磁场概念和空间分布的抽象性以及数学公式的复杂性,电磁学一直是大学物理课程教学中的难点。为使学生获得直观的理解,需要在相关教学中采用可视化的教学方法,将电、磁场大小与方向的空间分布进行展示。针对这一问题,以“载流螺线管周围的磁场分布”作为教学实例,开展基于Matlab的可视化教学研究。通过采用逐点数值计算的方法,精确和形象地展示磁感应强度大小与方向的空间分布,实现了磁场的可视化演示。在此基础上,通过Matlab GUI构建具有交互界面的教学演示平台。这一方法能够加深学生对于相关概念的理解,提升课堂的教学效果。Due to the abstraction of the concept and spatial distribution and the complexity of mathematical formulas,electromagnetism has always been a difficulty in the teaching of college physics.In order to make students obtain an intuitive understanding,visual teaching methods are suggested to show the spatial distribution regarding the magnitude and direction of electricity and magnetic fields.To this regard,a visual teaching case demonstration is done based on Matlab by taking “the magnetic field distribution around current-carrying solenoid” as an example.In this teaching practice,the visual demonstration of magnetic field can be realized by using the method of point-by-point numerical calculation,and by accurately and vividly demonstrating the spatial distribution of the magnitude and direction of magnetic induction intensity.On this basis,a teaching demonstration platform with interactive interface is built through the use of Matlab GUI.The teaching practice shows that this method can promote students’ understanding of relevant concepts and improve the effect in classroom teaching.
