Solution:
From Faraday's law, the induced electromotive force is \(e = \frac{dPhi}{dt}\). Converting minutes to seconds: \(e = \frac{2\text{ Wb}}{60\text{ s}} = \frac{1}{30}\text{ V}\).
If the flux associated with a coil varies at the rate of \(2\text{ Wb/min}\), then the induced emf in the coil is
