JEE AdvancedPhysicsElectromagnetic InductionMultiple correct+4 / −1
A circular insulated copper wire loop is twisted to form two loops of area AAA and 2A2A2A 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→\overrightarrow BB points into the plane of the paper. At t=0,t=0,t=0, the loop starts rotating about the common diameter as axis with a constant angular velocity ω\omegaω in the magnetic field. Which of the following options is/are correct? JEE Advanced 2017 Paper 1 Offline Physics - Electromagnetic Induction Question 17 English
  1. A
    The emf induced in the loop is proportional to the sum of the areas of the two loops
  2. B
    The amplitude of the maximum net emf induced due to both the loops is equal to the amplitude if maximum emf induced in the smaller loop alone
  3. C
    The net emf induced due to both the loops is proportional to cos⁡ ωt\cos \,\omega tcosωt
  4. D
    The rate of change of the flux is maximum when the plane of the loops is perpendicular to plane of the paper
