Magnetism: Basics and Phenomena

This lecture covers the basics of magnetism, starting with the discovery of magnetic effects attributed to Thalès de Milet. It explores the observation of magnetic phenomena, the interaction of magnetic fields with moving charges, and the concept of inductance. The instructor delves into the Maxwell-Ampere equation, magnetic permeability, and magnetic induction fields. The lecture also discusses the creation of magnetic fields by electric currents, the concept of magnetic dipoles, and the origin of magnetic properties in materials.
