A long cylindrical conductor of radius R carries a current I as shown below left The current density J nowever is not uniform over the cross section of the conductor but is a function of the radius according to J br where b is a constant Find an expression for the magnetic field B a at a distance r R and b at a distance r R measured from the axis I 12 71 R
