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.
