Faraday's Law of Electromagnetic Induction: Practice Problem & Solution
If the flux associated with a coil varies at the rate of \(2\text{ Wb/min}\), then the induced emf in the coil is
Short Solution (Best for NEET):
To solve this problem, we apply the core principles of Faraday's Law of Electromagnetic Induction. Understanding the underlying formula is key to arriving at the correct answer below:
From Faraday's law, the induced electromotive force is \(e = \frac{dPhi}{dt}\). Converting minutes to seconds: \(e = \frac{2\text{ Wb}}{60\text{ s}} = \frac{1}{30}\text{ V}\).
