Question:
(a) Find an expression for the magnetic energy stored per unit length in a coaxial transmission line consisting of conducting sleeves of negligible thickness, having radii a and b. A medium of relative permeability μr fills the region between conductors. Assume current I flows in both conductors in opposite directions.
