NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 12
A coil with 200 turns and an area of 0.05 m² is rotating at 1 revolution per second in a uniform magnetic field of 0.02 T. What is the maximum voltage generated in the coil?
A
0.628 V
B
0.314 V
C
0.157 V
D
1.256 V
Correct Answer
Option A
Detailed Explanation
Using the formula e₀ = NBA(2πn), and substituting N = 200, B = 0.02 T, A = 0.05 m², and n = 1 Hz, we get e₀ = 200 × 0.02 × 0.05 × 2 × 3.14 × 1 = 0.628 V.
