A circular insulated copper wire loop is twisted to form two loops of areas A and 2A, as shown. The crossing wires are electrically insulated. The entire loop rotates about the common diameter with constant angular speed ω in a uniform magnetic field B into the page. Choose the correct statements.

Select all that apply

• Option A

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

• Option B

  The net induced emf due to both loops is proportional to cosωt

• Option C

  The induced emf is proportional to the sum of the two loop areas

• Option D

  The maximum net-emf amplitude equals the maximum-emf amplitude of the smaller loop alone
