Question

A circular insulated copper wire loop is twisted to form two loops of area A and 2A as shown in the figure.
At the point of crossing the wires remain electrically insulated from each other. The entire loop lies in the
plane (of the paper). A uniform magnetic field ￫B points into the plane of the paper. A uniform magnetic
field ￫B points into the plane of the paper. At t = 0, the loop starts rotating about the common diameter as
axis with a constant angular velocity ???? in the magnetic field. Which of the following options is/are
correct?
[A] The rate of change of the flux is maximum when the plane of the loops is perpendicular to plane of the
paper.
[B] The net emf induced due to both the loops is proportional to cos ????t.
[C] The emf induced in the loop is proportional to the sun of the areas of the two loops.
[D] 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.
