MHT CET 2023 Physics question
A magnetic field of T acts at rights angles to a coil of area 100 cm 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
The flux linkage initially is Wb (using ), and finally zero (coil removed from the field). Average emf: , so
