An infinitely long straight solenoid of radius R and with n turns per unit length carries a current I. i. Show that the magnetic field B inside the solenoid may be written B = Moni and is zero outside the solenoid. ii. Use the example of the solenoid to explain why the magnetic vector potential is considered to be more fundamental than the magnetic field B. iii. Explain how a 'back emf' arises from Maxwell's equations if the current in the solenoid changes.
