In the figure shown below, you see a cross section of a weird coaxial cable. The regions in the figure are described as Region I: A steel wire of radius a = 10.0000 cm, with a current density of J = J₁r, where J₁ =12.0000 in the appropriate units. Region II: A section of insulating material with an outer radius b = 20.0000 cm. Region III: A cylindrical shell of steel outer radius c = 30.0000 cm with a current density of JIII J3=8.0000 in the appropriate units. The current density JIII moves in the opposite direction of Jr. where Region IV: The air outside the coaxial cable. C 10 I II III IV The magnitude of the magnetic field at r = 35.0000 cm is, in nT and to two decimal places, (1 nT=1 x 10⁹T)
