Follow along as we dissect the side view of a current-carrying wire loop rotating in a magnetic field. Unravel the concept of increasing magnetic flux from initial to final positions, triggering Lenz's law and the creation of an induced magnetic field. Witness the magic of back emf opposing the original current, impacting electric motor behavior. Real-world examples, like a dimming light in sync with a motor's start-up, bring theory to life. \n
