Answer:
Part a)
Part B)
Part C)
Explanation:
Part a)
Magnetic field due to a long ideal solenoid is given by
n = number of turns per unit length
now we know that magnetic field due to solenoid is
Now magnetic flux due to this magnetic field is given by
Part B)
Now for mutual inductance we know that
now we have
Part C)
As we know that induced EMF is given as
