When a current of 3 A through coil A is reversed

Two coils, A and B, have self-inductances of 120 μH and 300 μH respectively. When a current of 3 A through coil A is reversed, the deflection on a fluxmeter connected across B is 600 μWb-turns. Calculate: (a) the mutual inductance between the coils; (b) the average e.m.f. induced in coil B if the flux is reversed in 0.1 s; and (c) the coupling coefficient.
