A long, cylindrical conductor of radius R carries a current I as shown in Figure P30.36. The current density J, however, is not uniform over the cross-section of the conductor but rather is a function of the radius according to J = br, where b is a constant. Find an expression for the magnetic field magnitude B (a) at a distance r1 < R and (b) at a distance r2 > R, measured from the center of the conductor.
