Question: 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 I is 6.52 A, the average flux through each tum of solenoid 2 is 0.0320 Wh.
(a) What is the mutual inductance of the pair of solenoids?
(b) When the current in solenoid 2 is 2.54 A, what is the average flux through each turn of solenoid I?
