In 1831, Michael Faraday discovered that when a conductor is moved through a magnetic field, an electric current is generated in the conductor. This phenomenon is known as ElectroMagnetic Induction (EMI). Faraday’s law of induction states that the magnitude of the induced EMF in a circuit is proportional to the rate of change of the magnetic flux through the circuit.

The faradays constant (F) is defined as F=N⋅Φ0⋅B−1. Where N = number of turns in the coil, Φ0 = weber, and B = tesla. The SI Unit for faradays constant is (volt second)/(weber meter^2).

In summary, Faraday’s law explains how an electromotive force (emf) can be generated by moving a magnet near a wire. It also quantifies what happens: The size of the emf depends on how fast you move the magnet and on how many loops of wire there are.
