NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 12
A coil with 200 turns, an area of 0.05 m², and rotating at 1 revolution per second is placed in a uniform magnetic field of 0.02 T perpendicular to the axis of rotation. What is the maximum voltage generated in the coil?
A
256 V
B
0.628 V
C
0.314 V
D
0.157 V
Correct Answer
Option A
Detailed Explanation
Using the formula e_0 = NBA(2πn), where N=200, A=0.05, B=0.02, and n=1, the maximum voltage e_0 = 200 × 0.02 × 0.05 × 2 × 3.14 × 1 = 1.256 V.
