MHT CET 2026 Physics question
A square loop of area 25 cm has a resistance of 10 . The loop is placed in uniform magnetic field of magnitude 40 T. The plane of the 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
The loop is pulled out uniformly in s, so the flux linked falls from to zero at a constant rate. m, so Wb. The induced emf is constant: V.
