NEET Physics Faraday's Laws MCQ Question
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?
Increasing the number of turns (N) of the coil.
Decreasing the area (A) of the coil perpendicular to the magnetic field.
Keeping the magnetic field (B) completely uniform.
Maintaining a constant angle (θ) between the magnetic field and the area vector.
Correct Answer
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.
