Question
The figure below shows a long conducting coaxial cable and gives its radii (R1=0.25m, R2=0.56m, R3=1.08m). The outer cable has a uniform current
density of J=268A/m², and the inner cable carries a current l=17.5A flowing in opposite direction. Assume that the currents in each wire is uniformly
distributed over its cross section. Determine the magnitude of the magnetic field in terms of Ho at a distance r=0.83m from the center of the
cable. Express your answer using one decimal place.
