Faraday’s Laws
According to the Faraday’s first law, whenever the amount of magnetic flux linked with a circuit changes, an emf is induced in it. Induced current is determined by the rate at which the magnetic flux changes.
Mathematically, the magnitude of the induced emf in a circuit is equal to the rate of change of magnetic flux through the circuit.
Induced emf `prop` Rate of change of magnetic flux
The flux linked with a circuit is given by `phi=t^3+3t-7`. The graph between time (X-axis) and induced emf (Y-axis) will be a
