1) Figure shows a cylindrical cross section of an infinitely
long conducting coaxial cable, which contains a cylindrical
conductor and a hollow cylindrical conductor). For inner
conductor, a uniformly distributed current (directed towards
out of page) of i1 = 3 A flows. For outer conductor, a
uniformly distributed current (directed towards into page) of
i2 = 5 A flows. Assume that a = 4 cm, b = 2 cm, and c = 1

An infinitely long conductive wire of radius A is inside a sheath of
infinite length and very thin radius b. The steady I goes through the
conductor wire and returns through the cylindrical sheath. The
current density is assumed to be uniform across the wire and
sheath. Write the statements of the magnetic, inside the wire, the
wire and the sheath and the sheath elsewhere.
