have calulalated the magnetic flux denisty using the equation for current carrying wires.  When putting the direction I said 'out of the page', is this correct.  Or do I not put a direction when using the equation- B = μ0·I/2·π·r.  the image I have attached is what I am talking about regarding the direction of the magnetic field.  Is adding a direction when using this equation neccessary?

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.
