A current with a constant current density of Js=1\π (A/m2) in the +z direction from the a=2m radius wire is homogeneously distributed in the cross section in the −z direction from the infinitely long cylindrical shell with inner radius b=3m and outer radius c=4m constant I=4 Ampere current is flowing. Accordingly, using the Ampere formula, calculate the magnetic field in regions rc.
