Consider a coaxial cable with a central conducting wire (r=1mm) surrounded by an outer coaxial conducting sheath (rinner=3mm,router=3.2mm) as shown. A current i=300mA flows down the center wire (into the page) and back through the conducting sheath (out of the page).

The greatest magnitude of the magnetic field will be at the center of the coaxial cable, between the inner and outer conducting sheaths.
