Coaxial cable

A coaxial cable consists of an inner solid cylindrical wire of radius 2mm 2 \, \text{mm} and an outer conducting hollow cylinder of radius 4mm 4 \, \text{mm} , which each carry a current of magnitude 100mA 100 \, \text{mA} . If the currents travel in opposite directions, what is the magnitude of the magnetic field outside of the cable a distance of 1cm 1 \, \text{cm} measured perpendicularly from the central axis of the inner wire?
