Final answer:
Faraday's law of electromagnetic induction helps determine the induced emf in a conducting loop when there is a changing magnetic flux within the loop.
Step-by-step explanation:
Faraday's law of electromagnetic induction helps determine the induced emf (electromotive force) in a conducting loop when there is a changing magnetic flux within the loop. According to Faraday's law, the induced emf is directly proportional to the change in magnetic flux (Φ) and is inversely proportional to the change in time (Δt). Additionally, the number of turns in the coil (N) affects the magnitude of the induced emf.
