NEET Physics (general) MCQ Question
Type: MCQ-numerical-Medium-Class 12
If a coil with 100 turns and an area of 0.10 m² is placed in a uniform magnetic field of 0.01 T and rotates at 0.5 revolutions per second, what is the maximum voltage generated in the coil?
A
0.314 V
B
0.628 V
C
0.157 V
D
1.256 V
Correct Answer
Option A
Detailed Explanation
Using the formula for maximum voltage generation, e₀ = NBA(2πn), where N = 100, B = 0.01 T, A = 0.1 m², and n = 0.5 Hz, the calculation yields 0.314 V.
