Based on his experiments we now have *Faraday’s law* according to which *the amount of voltage induced in a coil is proportional to the number of turns of the coil and the rate of changing magnetic field.*

- AC generator works on the principle of electromagnetic induction.
- The working of electrical transformers are based on the electromagnetic induction.
- The magnetic flow meter is based on the electromagnetic induction.

*Mathematically, the induced voltage can be given by the following relation:*

e = N × dΦ / dt |

*Where,*

**e**is the induced voltage (in volts)**N**is the number of turns in the coil**Φ**is the magnetic flux – the amount of magnetic field at a surface (in Webbers)**t**is the time (in seconds)

The significance of this discovery is a way of producing electrical energy in a circuit by using magnetic fields and not just batteries. Everyday machines like motors, generators and transformers work on the principle of electromagnetic induction.
