Given a solenoid that has N1 turns, a length L1 and a radius r1 where a current running through is increasing from I1 to I2 in t seconds. A second solenoid coaxial with the first has N2 turns, a length L2, a radius r2 and a resistance R. Note that both solenoids are not connected, meaning the second is not connected to a source. Give the expression of:
a) The initial magnetic field the first solenoid creates inside its coil
b) The initial magnetic flux through each loop of the second solenoid
c) The final magnetic flux through each loop of the second solenoid
d) The average emf induced in the loop
e) The average current induced in the second solenoid during the time t
f) Explain the theory behind the direction of the induced emf including drawings.
