Final answer:
Faraday's law of induction states that the EMF induced in a loop is proportional to the change in magnetic flux through the loop.
Step-by-step explanation:
Faraday's law of induction states that the EMF induced in a loop of wire is proportional to the change in the magnetic flux through the loop. This principle is reflected by the equation emf = -N ΔΦ / Δt, where N is the number of turns in the coil, ΔΦ is the change in magnetic flux, and Δt is the change in time. The negative sign in Faraday's law is a representation of Lenz's law, which indicates that the direction of the induced current is such that it opposes the change in magnetic flux that produced it. To summarize, Faraday's law connects the induced EMF to the rate of change of magnetic flux through the loop, demonstrating the concept of electromagnetic induction.
