A long straight conductor of circular cross section of radius R carries a current i whose current density J is assumed Jo R to be varying with radial distance r as J J Magnetic field outside varies as Magnetic field inside varies as where J is a positive constant then 2 Jolor 3R HoJo R 3r Inside the conductor graph between magnetic field and radial distance is parabolic outside the conductor graph between magnetic field and radial distance is hyperbolic
