A solenoidal coil with 21 turns of wire is wound tightly around another coil with 350 turns. The inner solenoid is 21.0 cm long and has a diameter of 2.00 cm. At a certain time, the current in the inner solenoid is 0.150 A and is increasing at a rate of 1800 A/s. Part A For this time, calculate the average magnetic flux through each turn of the inner solenoid. Express your answer in webers. ΑΣφ Wb Part B For this time, calculate the mutual inductance of the two solenoids. Express your answer in henries. ? M = H
