MHT CET 2025 Physics question
A magnetic field 4 x T acts at right angles to a coil of area 100 with 50 turns. The average e.m.f. induced in the coil is 0.1 V, when it is removed from the field in time 't'. The value of 't' is
Answer: (C)
Solution
Initial flux through turns: Wb-turns; final flux is zero. Average e.m.f. , so $t =
