Faraday's Law of Electromagnetic Induction: Practice Problem & Solution
Induced emf produced in a coil of area \(A\) rotating with angular velocity \(\omega\) in a magnetic field \(B\) is equal to \[\frac{\sqrt{3}BA\omega}{2}\], when the angle between the area vector of the coil and direction of magnetic field is
Solution Explained:
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:
The induced emf is given by \(e = BA\omega \sin\theta\). Given \(e = \frac{\sqrt{3}}{2}BA\omega\), we have \(\sin\theta = \frac{\sqrt{3}}{2}\), which yields \(\theta = \frac{\pi}{3}\).
