Motional emf via Faraday’s Law (5:54)
In today's episode, we explore an alternative derivation of the motional emf equation, revealing a fascinating perspective. Picture a conductor moving right on parallel metal rails connected by a wire in a uniform magnetic field. A force propels the conductor, creating a conducting loop with increasing area. Lenz's law predicts an induced current in the loop, opposing the change in flux. Bo determines the current direction using the righthand rule. We then employ Faraday's law to find the induced emf, discovering that it matches our previous derivation. Join us as we delve into the nuances of theta and uncover the intricacies of motional emf.
