Relativity and electricity

Several facets of the special theory of relativity are reviewed, commencing with the Lorentz equations and culminating in the force transformation law. The basic equations of electrostatic theory are then formulated, after which a relativistic transformation of Coulomb´s law is undertaken, the result being the Lorentz force law. Time-varying electric and magnetic fields are defined as constituent terms of the Lorentz force expression and are then shown to satisfy Maxwell´s equations. The development includes derivations of the relativistic transformation laws for sources and fields.
