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 500 turns, while solenoid 2 has 300 turns. When the current in
solenoid 1 is 3.21A, the average flux through each turn of solenoid 2 is
0.0120Wb. When the current in solenoid 2 is 1.23A, find the average flux
through each turn of solenoid 1.
