Consider a straight, infinitely long, current conductor lying on the z – axis. Which one of the following plots (in linear scale) qualitatively represents the dependence of H_{\phi } on r, where H_{\phi } is the magnitude of the azimuthal component of magnetic field outside the conductor and r is the radial distance from the conductor?

Consider a straight, infinitely long, current conductor lying on the z – axis. Which one of the following plots (in linear scale) qualitatively represents the dependence of

H_{φ }

on r, where

H_{φ }

is the magnitude of the azimuthal component of magnetic field outside the conductor and r is the radial distance from the conductor?
