MHT CET 2023 Physics question
A square loop of area 25 cm<sup>2</sup> has a resistance of 10 . This loop is placed in a uniform magnetic field of magnitude 40 T. The plane of loop is perpendicular to the magnetic field. The work done in pulling the loop out of the magnetic field slowly and uniformly in one second, will be
Answer: (B)
Solution
Initial flux Wb; finally the flux is zero. Pulled out uniformly in s, the induced emf is V (constant). Current A. Work done
