wirePr2riRA hollow pipe and a current carrying wire outside of it. Drawing not to scale.The figure above shows a long hollow pipe centred at the origin, with outside radius R carrying a uniform currentIo into the page. An infinitely long, straight wire runs parallel to the pipe at a distance R+rı+r2 from its center.8. Let ri2R, r2R. Calculate the magnitude and direction of the current in the wire that would cause the Hfield at P to have the same magnitude, but opposite direction, as the resultant field at the centre of the pipe. Verifyexplicitly your solution by showing that, with your Iw, Ĥ(r2) = –Ħ(0).
