A long, cylindrical conductor of radius R carries a current I as shown in the figure below. The current density J, however, is not uniform over the cross section of the conductor but is a function of the radius according to J = 4br2, where b is a constant.   Find an expression for the magnetic field magnitude B at the following distances, measured from the axis in part a and b. (Use the following variables as necessary:  ?0, r1, r2, b, R.)   Note: See image for the original question and figure
