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.

Question

A wire carries a steady current of 2.60 A. A straight section of
the wire is 0.850 m long and lies along the y-axis within a
uniform magnetic field, B=(1.70 k) T. If the current is in
the negative y-direction, what is the magnetic force (in N) on
this section of wire? (Note: i, j, and k are the cartesian unit
vectors.)
