PhysicsElectromagnetic InductionMHT CET

Two coils P and Q are separated by some distance. When a current of 3 A flows through coil P, a magnetic flux of Wb passes through Q. No current is passed through Q. When no current passes through P and a current of 2 A passes through Q, the flux through P is

Answer: (B)

Solution

Mutual inductance is reciprocal, so H and the flux through P is
