The figure below shows a long conducting coaxial cable and gives its radii (R1=0.2m, R2=0.59m, R3=1.18m). The inner cable has a uniform current density of J=118A/m2, and the outer cable carries a current I=24A 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 at a distance r=0.85m from the center of the cable. Express your answer using two decimal places.
