Challenge: Michael Faraday (1791–1867), who is generally credited as the discoverer of electromagnetic induction (in 1831), discovered the relationship between voltage (V), the force that creates a current in a wire, and the magnetic flux.
Faraday’s law of magnetic induction relates voltage to the change in magnetic flux (ΔΦM) and the time interval (Δt). Based on the observations you have made, what is Faraday’s law? Check your answer with your teacher.
Faraday's law states that the induced electromotive force (EMF) in any closed circuit is equal to the negative rate of change of magnetic flux through the circuit. Mathematically, it can be expressed as:
EMF = -d(ΦM)/dt
where EMF is the induced electromotive force, ΦM is the magnetic flux, and dt is the time interval.
