There are two coils A and B seperated by some distance. If a current of 2 A flows through A, a magnetic flux of 10-2 Wb passes through B (no current through B). If no current passes through A and a current of 1 A passes through B, what is the flux through A?

Mutual inductance = 10-2/2=5mH

Flux = 5 ×10–3 ×1=5 ×10–3Wb.
