a pair of adjacent coils have mutual inductance of 1.5 H .if the current in one coil changes from 0 to 20 A in 0.5s what is the change in flux linkage with other coil

Flux linkages with the other coil are
N Φ = MI1
So, change is flux linkages with the other coil are
Δ (NΦ) = MΔ I1 = 1.5 x (20 – 0) = 30 Wb
