MHT CET 2024 Physics question
The magnetic field of T acts at right angles to a coil of all 100 cm with 50 turns. The average e. m. f. induced in the coil 0.1 V, when it is removed from the field in time t. The value of 't (in second)
Answer: (A)
Solution
The coil is perpendicular to the field, so initially the flux per turn is Wb, and finally (coil removed from the field). Average induced emf , so
