The magnetic flux linked with the coil varies with time asφ= 3t2 +...
The equation that describes the variation of magnetic flux linked with a coil with time is given by Faraday's law of electromagnetic induction:
ε = -dΦ/dt
where ε is the induced electromotive force (emf) in the coil, Φ is the magnetic flux linked with the coil, and dt is the change in time. The negative sign indicates that the induced emf is in the opposite direction of the change in magnetic flux.
This equation shows that the induced emf in a coil is directly proportional to the rate of change of magnetic flux. Therefore, if the magnetic flux linked with the coil varies with time, the induced emf in the coil will also vary with time.
