Physics-Faraday's Laws
NEET Physics Faraday's Laws MCQ Question
Type: MCQ-numerical-Hard-Class 12
A coil of 200 turns is in a uniform magnetic field that changes at a rate of 0.02 Wb/s. What is the magnitude of the induced emf in the coil?
A
0 V
B
0 V
C
0.4 V
D
0.02 V
Correct Answer
Option A
Detailed Explanation
According to Faraday's law, the induced emf in a coil is given by -N(dΦ/dt). With N = 200 and dΦ/dt = 0.02 Wb/s, the induced emf is 200 * 0.02 = 4.0 V.
