摘要
《电磁学》中基本概念、基本规律理论性强、场图复杂.针对离散点电荷系在空间产生的场分布、静电场中导体的静电感应现象、静电场中电介质的极化现象等典型静电类电磁问题,利用Matlab中的偏微分方程工具箱(PDEtool)、数学物理方程进行可视化仿真实验设计.仿真结果中电场线、等势线的分布很好地体现出典型电磁现象及相关物理性质,有助于信息技术条件下的教学方法改革.
Basic concepts and principles in Electromagnetism have abstract reasoning and complicated field-map. Typical electrostatic electromagnetic problems such as the electric field distribution of discrete point-charge group in the space, electrostatic induction phenomenon of conductor in electrostatic field, and polarization phenomenon of dielectric in electrostatic field, can be visually simulated by PDEtool in Matlab and Mathematical physics equations. The simulation results show that the electric field lines and equipotential lines describe well the electromagnetic phenomena and physical properties. The simulation design is beneficial to teaching reform by information technology.
