4. A very long coaxial cable consists of a solid cylindrical inner conductor of radius a, surrounded by an outer cylindrical conductor with inner radius b and outer radius c. The inner wire and outer wire (cylinder) do not touch each other. The inner wire has a current in it I, and the outer wire has a current in it I,. 4 is out of the page and Iz is into the page. Use Ampere's law to find an equation for the magnetic field strength (a) between the two wires (ac). (c) If I, and I, were equal but still opposite in direction what would be the magnetic field strength outside of the cable (r>c)?
