Foundations of Electricity and Magnetism (E&M)

Understanding electricity and magnetism is the bedrock of modern physics and engineering, yet these concepts can often feel abstract. Start with the fundamental principles that govern how charges interact and fields propagate. By the end of this course, you will move beyond rote memorization of formulas to gain a deep conceptual understanding of electric and magnetic phenomena. You will be able to analyze basic circuits, calculate field strengths, and understand the relationship between changing fields and electromagnetic waves. What you'll learn: * Understand the foundational concepts of charge, force, and electric fields using Coulomb's Law and Gauss's Law. * Apply principles of electric potential and energy storage in capacitors and dielectric materials. * Master the principles of magnetostatics, including the Biot-Savart Law and Ampere's Law, to calculate magnetic fields. * Analyze basic DC and AC circuits using Ohm's Law and Kirchhoff's Rules, focusing on inductors and their role in energy transfer. * Grasp the principles of electromagnetic induction (Faraday's Law) and the generation of fundamental electromagnetic waves. * Practice solving complex problems involving field interactions, current flow, and basic material properties. The course begins with electrostatics and potential theory, progresses through magnetostatics and induction, and culminates in an introduction to Maxwell's equations and their role in describing electromagnetic waves. Written exercises and conceptual explanations reinforce theoretical knowledge throughout the text. This course is designed for absolute beginners in physics or students needing a rigorous refresher in foundational concepts; no prior knowledge of calculus-based physics is assumed. Begin your journey into the fundamental forces that shape the physical world today.
