The coefficients of mutual inductance when magnetic flux changes by 2×10−2 Wb and current changes by 0.01 A, will be

Coefficient of mutual induction of two coils is equal to the number of magnetic flux (ϕ) linkages in one coil when a unit current (i) flows in the other.Therefore, M=ϕiGiven, ϕ = 2 × 10−2 Wb, i=0.01 AM=2×10−20.1=2 H
