The figure below shows a long conducting coaxial cable and gives its radii (R1=0.21m, R2=0.63m, R3=1.06m). The outer cable has a uniform current density of J=280A/m², and the inner cable carries a current l=7.9A 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 He at a distance r=1.48m from the center of the cable. Express your answer using once decimal place. R R3
