Question 186 of 200

Multiple Choice

Decreasing area of coil

14.77%

Explanation:

Decreasing magnetic field

8.78%

Explanation:

Increasing area of coil

72.46%

Explanation:

As, ε = BΔA/Δt

Thus, induced emf can be increased by increasing area of coil.

Hence, option C is correct.

Slowing down speed of coil

3.99%

Explanation:

Explanation

As, ε = BΔA/Δt

Thus, induced emf can be increased by increasing area of coil.

Hence, option C is correct.
