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.
