A circular insulated copper wire loop is twisted to form 2 loops of area A and 2A. At the point of crossing the wires are insulated. The loops lie in the plane of the paper. A magnetic field, B, points into the paper. At t=0 the loops start rotating at angular velocity . Which of the statement(s) is/are correct?
a) The EMF induced in the loop is proportional to the sum of the areas of the 2 loops.
b) The amplitude of the maximum net EMF induced due to both the loops is equal to the amplitude of max EMF induced in the small loop.
c) The net EMF induced due to both loops is proportional to cost.
d) The rate of change of the flux is maximum when the plane of the loops is perpendicular to the plane of the paper.
