Question

A circular insulated copper wire loop is twisted to form two loops of area

• A. The emf induced in the loop is proportional to the sum of the areas of the two loops
• B. The amplitude of the maximum net emf induced due to both the loops is equal to the amplitude of maximum emf induced in the smaller loop alone
• C. The net emf induced due to both the loops is proportional to $\cos \omega t$
• D. The rate of change of the flux is maximum when the plane of the loops is perpendicular to plane of the paper

Answer 1

Answer: (D)

The rate of change of the flux is maximum when the plane of the loops is perpendicular to plane of the paper
