Using Simulations to Highlight the Role of Electromagnetism in Special Relativity

Physics Education Research (PER) studies have demonstrated that undergraduate students struggle with fundamental principles from Electromagnetism (EM) and Special Relativity (SR). However, few studies have approached the intersection of the two subjects: the role which EM played in inspiring the development of SR. To address this issue, this paper presents two simulations which highlight the fundamental role of electromagnetism in special relativity. The first simulation demonstrates the Lorentz Transformations and the origin of the Gamma Factor from Maxwell's Equations. The second simulation offers an experiential introduction to the Biot-Savart Law, from which the Displacement Current in Ampere-Maxwell's Law can be derived. These programs may be useful in an undergraduate electromagnetism course. The simulations discussed in this paper are available at the link given in the footnote.
