Magnetism, Induction, and AC Circuit Fundamentals

Understanding how magnetic fields are generated and interact with changing currents is essential for modern electronics and power systems. This course demystifies the fundamental physics governing electromagnetism’s second half, providing a solid theoretical foundation. By the end of this course, you will be able to apply fundamental physical laws to calculate magnetic fields, predict inductive behavior, and analyze the performance of alternating current circuits. What you'll learn: * Understand the definition and characteristics of magnetic fields and the forces they exert on moving charges and currents. * Apply Ampere's Law and the Biot-Savart Law to calculate magnetic fields generated by various current configurations. * Master the principles of electromagnetic induction, including Faraday's Law and Lenz's Law, and how they relate to inductors and generators. * Analyze the transient and steady-state behavior of circuits containing resistors, inductors, and capacitors (RLC circuits) under alternating current (AC). * Practice using phasors and impedance concepts to solve complex AC circuit problems, including resonance and power factor. The course begins with foundational concepts of magnetic fields and forces, systematically moving through the major laws of electromagnetism. We then transition to the practical application of these laws in analyzing the behavior of inductors and complex AC circuits. This course is designed for absolute beginners interested in foundational physics or electrical engineering principles. No prior knowledge of advanced calculus or electromagnetism is required.
