摘　　要：将抽象的电磁场理论融入高科技、现代化的科学实践中是电磁场课程的时代使命。电磁场课程中的虚拟仿真环节可以让学生深入理解电磁理论,培养学生的工程思维能力和工程实践能力。针对电磁场抽象性特点,设立层层深入的虚拟仿真环节,提供多重仿真手段,从基础性的电磁场理论可视化,到研究型的电磁场优化和解算,再到探索性的电磁器件设计,为学生提供自主探索和研究的平台,引导学生会用“场”的观点去观察、分析和解决实际工程问题。形成基于“研究型、项目式”学习的考核体系,做到考核公平、公正,有据可循。依托虚拟仿真专题,同时改革了电磁场理论授课和实验部分,形成合力,培养适应现代工业的“电磁场”类人才。electromagnetic theory into high-tech and modern scientific practice.The electromagnetic simulations in the course can help students better understand the electromagnetic theory and cultivate students’engineering thinking ability and engineering practice ability.According to the characteristics of the course,electromagnetic simulations of different levels are provided,from the simple visualization to the optimization of the electromagnetic field,with the final goal of designing electromagnetic devices.This way,a platform is provided for the students to carry out research independently.The students have learnt to observe,analyze and solve engineering problems from the perspective of electromagnetic fields.At the same time,a system is designed to ensure the fairness of the assessment.The teachings of the theoretical part and the experimental part are reformed together,which forms a joint force to cultivate electromagnetic field talents who are adapted to the modern industry.
