Foundations of Magnetism, Electromagnetic Induction, and AC Circuits

Understanding how electricity and magnetism interact is fundamental to modern technology, powering everything from electric motors to wireless chargers. This text-based course guides you through these essential physics concepts without requiring prior advanced knowledge. By completing this course, you will progress from basic magnetic definitions to analyzing alternating current (AC) circuits, building a strong conceptual foundation for engineering, physics exams, or personal technical development. What you'll learn: 1. Understand the fundamental properties of magnetic fields and magnetic forces on moving charges. 2. Analyze electromagnetic induction and apply Faraday's and Lenz's laws to practical scenarios. 3. Explore the mechanics of self-induction, mutual induction, and how transformers operate. 4. Master the behavior of alternating current (AC) in resistors, inductors, and capacitors. 5. Calculate resonance and power factor in AC circuits with step-by-step written examples. 6. Discover modern applications of electromagnetism, including wireless power transfer and renewable energy systems. The course begins with essential terminology and magnetic field theory before moving systematically into induction laws, AC circuit analysis, and real-world engineering applications. This course is designed for beginners, self-directed physics students, and anyone preparing for introductory engineering and physics examinations. No advanced prerequisites are required.
