A long coaxial cable consists of two thin-walled conducting cylinder carries a steady current 0.1A, and the outer cylinder provides the return path for that current. The current produced a magnetic field between the two cylinders. Find the energy stored in the magnetic field for length 5 m of the cable. Express answer in Nj (use 1 n^2 = 0.7).
