A tightly wound solenoid with radius R and length ℓ >>R is composed of N turns of conducting wire. The solenoid carries a slowly varying current I (t) and experiences a voltage drop V (t) over its length. Show that

where E_z is the average electric field along the solenoid axis and E_θ is the tangential electric field at the surface of the solenoid.
