MHT CET 2026 Physics question
A coil of effective area 3 m is placed at right angles to a magnetic field of induction 0.05 Wb/m. If the field is decreased to 20% of its original value in 10 second, the e.m.f. induced in the coil will be
Answer: (B)
Solution
Initial flux Wb. Final field is 20% of the original: Wb/m, so Wb. Change in flux Wb. Induced e.m.f. $e =
