Self Inductance and Mutual Inductance in General Physics - Lesson 20.3

Explore the concepts of self inductance and mutual inductance in this comprehensive physics lesson. Discover how changing currents create magnetic fields and induce electromotive forces in conducting loops, following Faraday's Law and Lenz's Law. Learn about the SI unit for inductance, the Henry, and its relationship to volts, seconds, and amperes. Delve into the principles of mutual inductance and its application in transformers, understanding how they can step up or step down potential differences in AC circuits. Follow along as the instructor demonstrates these concepts through a practical transformers problem, providing a clear understanding of how adjusting the number of turns in primary and secondary coils affects transformer operation.
