Electromagnetic Induction | Lenz's Law | A-level Physics

In this video, we discuss Lenz's law, an important principle of electromagnetic (EM) induction. This video is the third video in our induction playlist, and picks up from where the previous video ended. You'll see how the energy puzzle at the end of that video gets resolved here, and how Lenz's law relates to conservation of energy. We pose a couple of small questions throughout to keep the video interactive.    / @forestlearn
