L4.2 Review of Maxwell's equations: Faraday's law and electromagnetic induction

Welcome to this Lecture on Classical Electrodynamics! This session dives deep into the foundational principles of electromagnetic induction, starting from the concept of EMF and building up to Faraday's groundbreaking experiments and the mathematical formulation of his law. Based on the rigorous framework of J.D. Jackson's Classic Electrodynamics, this lecture is perfect for university students and physics enthusiasts. We'll break down the three key experiments by Faraday that led to the discovery that a changing magnetic flux induces an electromotive force (EMF) and, consequently, an electric field. We clarify the crucial difference between the magnetic force (responsible for motion in experiment 1) and the induced electric field (responsible for current in experiments 2 & 3). In this video, you'll learn: The definition of EMF and its relation to magnetic flux (dΦ/dt). A review of the Lorentz Force law and how magnetic forces act on moving charges. A detailed analysis of Faraday's three experiments on induction. The critical conceptual leap: a changing magnetic field generates an electric field. The step-by-step derivation of the integral form of Faraday's Law from EMF. The application of Stokes' theorem to arrive at the differential form of Maxwell's equations.
