“…Efforts to develop stereoscopic VR visualizations for physics began in the mid-1990s [1][2][3] and continue to the present day (see, e.g., Refs. [4][5][6][7][8][9] and references therein) as the technology improves.…”

Recent years have seen a resurgence of interest in using virtual reality (VR) technology to benefit instruction, especially in physics and related subjects. As VR devices improve and become more widely available, there remains a number of unanswered questions regarding the impact of VR on student learning and how best to use this technology in the classroom. On the topic of electrostatics, for example, a large, controlled, randomized study performed by Smith et al. [A controlled study of stereoscopic virtual reality in freshman electrostatics,

“…The visualizations in the AR and VR modes can help us to comprehend the physical processes and phenomenon, and especially those, which cannot be seen with our eyes or reproduced. Thus, in the works of Franklin and Ryder [19], Pirker et al [44], and Sunders et al [52] virtual environments were developed, which allow studying, controlling, and interacting with electromagnetic phenomena. Another example of visualizing the complex conceptions is the OpenRelativity project [53].…”

Currently, computer‐based training systems, such as virtual laboratories (VLs), are becoming more common not only in universities but also in secondary schools. For physics, VLs are of great importance, as they allow simulating processes that cannot be seen or reproduced. Technologies such as augmented reality (AR) and virtual reality (VR) help us to create such physical visualizations. This study presents a VL, which allows users to solve various physical practical tasks or problems with the help of three‐dimensional process visualizations performed in three different ways, namely desktop VR, AR, and VR using a Leap Motion controller. This study describes in detail the functionality and implementation of a VL. As an experiment, three schools were provided with the necessary equipment and software. Fifty pupils of the 9th grade used the developed VL for half of the academic year, after which they took part in a comprehensive survey. About 88% of them found the laboratory useful for studying physics. The children were satisfied with its functionality and usability. Interviews with teachers helped us to understand which of the three visualization methods is preferable for them and children in the present environment.

“…Visualization of field lines can help in better understanding complex field configurations generated by non-trivial particle trajectories, and knowledge of field lines can also be used to estimate the electric field strength, due to the interconnection between local field line density and field strength as embodied by the zero divergence of the electric field in source-free space. Thus, the question how to efficiently calculate and draw field lines for arbitrarily moving point charges has been repeatedly considered in the literature [3][4][5][6][7][8][9]. Here, we present an efficient and relatively simple way of how to find and draw electric field lines of an arbitrarily moving charge by deriving a compact auxiliary equation for a unit vector pointing from the retarded position of the charge to a specific field line position.…”

Generation of electromagnetic fields by moving charges is a fascinating topic where the tight connection between classical electrodynamics and special relativity becomes particularly apparent. One can gain direct insight into the fascinating structure of such fields by visualizing the electric field lines. However, the calculation of electric field lines for arbitrarily moving charges is far from trivial. Here, we derive an equation for the director that points from the retarded position of a moving charge towards a specific field line position, which allows for a simple construction of these lines. We analytically solve this equation for several special but important cases: for an arbitrary rectilinear motion, for the motion within the wiggler magnetic field of a free electron laser, and for the motion in a synchrotron. arXiv:1809.05868v2 [physics.class-ph]
