Studied on Faraday's Law of Induction. Faraday's Law of electromagnetic induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction.
Faraday's First Law:
- any change in the magnetic field of a coil of wire will cause an emf to be induced in the coil
- the emf induced is called induced emf and if the conductor circuit is closed, the current will also circulate through the circuit and this current is called induced current

Methods to change magnetic field:
- By moving a magnet towards or away from the coil
- By moving the coil into or out of the magnetic field
- By changing the area of a coil placed in the magnetic field
- By rotating the coil relative to the magnet
Faraday's Second's Law:
- the magnitude of emf induced in the coil is equal to the rate of change of flux that linkages with the coil
- the flux linkage of the coil is the product of the number of turns in the coil and flux associated with the coil

Watched some videos on how electromagnetic induction can generate electricity.

Faraday's Law Formula:
Where:
E = induced emf (V)
N = no. of turns in the coil
Φ = BA =magnetic flux (Wb)
t = time (s)

Found out that the induced current will be AC and the load (beacon light) is DC. Therefore, there should be an AC to DC converter circuit.
