a cylindrical conductor of radius R carries a current along its length. the current density J,however,is not uniform over the crosssection of the conductor but is a function of the radius as J = br, where b is a constant. find the expression for the magnetic field B: 1. at a distance r1 2. at a distance r2 > R, measured from the axis
