Two toroidal solenoids are wound around the same form so that the magnetic field of one passes through the turns of the other. solenoid 1 has 700 turns, and solenoid 2 has 400 turns. when the current in solenoid 1 is 6.52 a, the average flux through each turn of solenoid 2 is 0.0320 wb. (a) what is the mutual inductance of the pair of solenoids
