An approach emphasizing the complementarity of electric and magnetic fields within a weak relativistic approximation is suggested as a basis for presenting electromagnetism in an introductory university physics course. Within the electromagnetic unification approach, “magnetic force” and “electromagnetic induction” are each taught in a manner consistent with mechanics from a qualitative relativistic point of view. The Lorentz force and the magnetic flux rule are treated similarly, linking electrical and magnetic phenomena and improving the integrity and self-consistency of the course. The status of Faraday’s integral law is discussed and is shown to be of limited validity in this context.
