Physics-Faraday's Laws
NEET Physics Faraday's Laws MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a scenario where a coil with N turns is placed in a changing magnetic field. The induced emf (ε) in the coil is described by Faraday's law. Which of the following changes will increase the magnitude of the induced emf?
A
Increasing the number of turns (N) of the coil.
B
Decreasing the area (A) of the coil perpendicular to the magnetic field.
C
Keeping the magnetic field (B) completely uniform.
D
Maintaining a constant angle (θ) between the magnetic field and the area vector.
Correct Answer
Option A
Detailed Explanation
According to Faraday's law, the magnitude of the induced emf is directly proportional to the number of turns (N) in the coil. Increasing N increases the total induced emf.
