![]() Find the change in magnetic flux (ΔΦ B) by subtracting the initial magnetic flux from the final magnetic flux.Calculate the magnetic flux (Φ B) at the initial and final states using the formula for magnetic flux.Determine the number of turns (N) in the coil.Where B is the magnetic field strength, A is the area of the coil, and θ is the angle between the magnetic field direction and the normal to the coil’s surface. To calculate the magnetic flux, use the following formula: Where N is the number of turns in the coil, ΔΦ B is the change in magnetic flux, and Δt is the change in time. In the case of a coil with multiple turns, Faraday’s law can be modified as follows: Here, EMF represents the induced electromotive force, Φ B denotes the magnetic flux, and t stands for time. Faraday’s Lawįaraday’s law states that the induced EMF in a closed loop is equal to the negative rate of change of the magnetic flux through the loop: ![]() ![]() This article will guide you through the process of calculating induced EMF in a coil due to a changing magnetic field. This phenomenon, known as electromagnetic induction, is governed by Faraday’s law of electromagnetic induction. Induced electromotive force (EMF) in a coil occurs when a changing magnetic field interacts with the coil. To calculate induced EMF in a coil, use Faraday’s law: EMF = -N*(ΔΦB/Δt), where N is the coil turns, and ΔΦB and Δt are changes in magnetic flux and time. ![]()
