There are two coils A and B separated 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?


Given: - current I = 2A

magnetic flux Φ = 10-2 Wb


for Φ = MI




Φ = 5×10-3
