Augmented reality in teaching of electrodynamics
Purpose - The purpose of this paper is to present an application of augmented reality (AR) in the context of teaching of electrodynamics. The AR visualization technique is applied to electromagnetic fields. Carrying out of numerical simulations as well as preparation of the AR display is shown. Presented examples demonstrate an application of this technique in teaching of electrodynamics. Design/methodology/approach - The 3D electromagnetic fields are computed with the finite element method (FEM) and visualized with an AR display. Findings - AR is a vivid method for visualization of electromagnetic fields. Students as well as experts can easily connect the characteristics of the fields with the physical object. Research limitations/implications - The focus of the presented work has been on an application of AR in a lecture room. Then, easy handling of a presentation among with low-hardware requirements is important. Practical implications - The presented approach is based on low-hardware requirements. Hence, a presentation of electromagnetic fields with AR in a lecture room can be easily done. AR helps students to understand electromagnetic field theory. Originality/value - Well-known methods like FEM and AR have been combined to develop a visualization technique for electromagnetic fields, which can be easily applied in a lecture room.
