The current produced due to induced EMF (electromotive force) is governed by Faraday's Law of Electromagnetic Induction, which states:

Where:

• $N$ = number of turns in the coil

• $Phi$ = magnetic flux = $B cdot A cdot costheta$ , where:

  • $B$ is the magnetic field strength

  • $A$ is the area of the coil

  • $theta$ is the angle between the magnetic field and the normal to the coil
