Explore the fundamental principles of inductors in this comprehensive 2-hour physics lecture covering AC transformers, solenoid self-inductance, magnetic and electrical energies, and toroidal inductance calculations. Begin with an introduction to the core concepts before diving into AC transformer theory and operation. Examine solenoid self-inductance properties and calculations, then analyze the relationship between energies in both magnetic and electrical systems. Conclude by investigating the specific inductance characteristics of toroidal configurations and their practical applications in electromagnetic systems.
