Question

A conducting ring of radius 1 m kept in a uniform magnetic field B of 0.01 T, rotates uniformly with an angular velocity 100 rad s\(^{-1}\) with its axis of rotation perpendicular to B. The maximum induced emf in it is

• A. 1.5\(\pi\)V
• B. \(\pi\)V
• C. 2\(\pi\)V
• D. 0.5\(\pi\)V
• E. 4\(\pi\)V

Hint:

The formula \( \epsilon = NBA\omega \sin(\omega t) \) is the principle behind AC generators. Here, since it's a single ring, the number of turns \( N \) is 1.

Answer 1

The Correct Option is B
