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

Two long straight current-carrying wires are
lined up parallel to one another in vacuum at a
distance d. Currents of I and I2 flow through
the wires, both in the same direction generating
the field of BM at a midpoint between them.
Write down an expression for BM in terms of
the currents running in each of the wires.
Assume vacuum permeability µo = 1. Please
"*" for products (e.g. B*A), "/" for ratios (e.g.
II *II
use
B/A) and the usual "+" and "-" signs as
1
appropriate. For R use 1/(A*B). For Greek
A*B
letters such as 1 or t use lambda and pi. Please
