Using the Cycloid as an Introduction to Transformations of "E" and "B" Fields
Frodyma, Marc; Le, My Phuong
Physics Teacher, v56 n5 p304-306 May 2018
The transformations of electric and magnetic fields are usually introduced by viewing systems such as a long, straight current-carrying wire and a parallel plate capacitor in two different reference frames. These well-known examples show that magnetism is a necessary consequence of augmenting electrostatics with relativity. Because they require the full apparatus of Lorentz contraction and Lorentz transformation of forces, they are often postponed until the upper-division undergraduate electrodynamics course.
