## What is Faraday's Law Calculator?

Faraday's Law Calculator is a physics/math calculator designed to find the voltage induced in a closed circuit quickly and easily.

Features:
- Instant calculation
- Results are copyable to other apps
- Formulas are included as references
- Supports up to 16 decimal places
- Supports various units for each input
- Lightweight app with a small size, optimized for everyday use

Faraday's law is a principle stating that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit, proportional to the rate of change of the flux linkage.

Faraday's law of induction is a fundamental law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)—a phenomenon called electromagnetic induction. It is the fundamental operating principle of transformers, inductors, and many types of electrical motors, generators, and solenoids.


Formula:

Φ = B * A
EMF = - N * dΦ / dt

Where:
EMF - induced emf
Φ - magnetic flux 
B - magnitude B
A - cross-sectional area of the coil
N - Number of coil turn
t - time in second
