The Faraday's Law Calculator will calculate the:

- Emf induced in a coil using the Faraday's Law

**Calculation Parameters:** Magnetic field and medium are considered as uniform; the conducting wire used for the coil is uniform and it has the same thickness everywhere.

ε_{i} = -*B × A*_{2} × cosθ_{2} - A_{1} × cosθ_{1}*/**∆t*

This formula derives from Faraday's Law of Induction:

ε_{i} = -*∆Φ*_{M}*/**Δt*
