本文提出了一种基于增强现实技术的电磁学教学实时可视化系统。它实时地给出了条形磁铁和铁片产生的磁场图像，而条形磁铁和铁片是用模拟的磁铁来表示的。在新提出的可视化系统中，这些模型被网络摄像头捕捉到，并对计算磁场所需的网格进行了变形。随后，在很短的时间内进行有限元分析，然后立即将磁场可视化。因此，可以实时地观察到由棒状磁铁产生的磁通线被吸引到一块铁上。此外，当用户移动模型时，根据模型的位置立即描绘磁通线。
In this paper, we propose a real-time visualization system utilizing Augmented Reality Technology for electromagnetics education. It gives an image of magnetic field generated by a bar magnet with a piece of iron in real-time, however the bar magnet and the piece of iron are represented by mock ones. In the newly proposed visualization system, these mocks are captured by a web camera, and mesh needed in the calculation of magnetic field is deformed. Subsequently, a finite element analysis is carried out in very short time and then the magnetic field is immediately visualized. Thereby, it is, in real-time, observable that magnetic flux lines generated by the bar magnet are attracted to a piece of iron. Moreover, when a user moves the mocks, the magnetic flux lines are immediately depicted according to the position of the mocks.
