NEET Physics Faraday's Laws MCQ Question
Consider a scenario where a coil is placed in a changing magnetic field such that the magnetic flux through the coil varies with time. According to Faraday's Laws, which factor will increase the magnitude of the induced emf in the coil?
Increasing the number of turns in the coil
Decreasing the area of the coil
Keeping the magnetic field constant
Decreasing the rate of change of magnetic flux
Correct Answer
Detailed Explanation
The induced emf is given by the equation ε = -N(dΦ/dt), where N is the number of turns. Increasing N increases the magnitude of the induced emf.
