Question: What is the effect of increasing the area of a loop in a uniform magnetic field on the induced emf?

Options:

1. Induced emf increases
2. Induced emf decreases
3. Induced emf remains the same
4. Induced emf becomes zero

Correct Answer: Induced emf remains the same

Solution:

The induced emf depends on the rate of change of magnetic flux, not directly on the area of the loop in a uniform magnetic field. Therefore, it remains the same if the magnetic field is constant.
