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.

The figure below shows the three loaded loops. Rings 1 and 2 have the same dimensions and radius
a, and Ring 3 has a larger radius b.
Rings 2 and 3 are located on one plane and Ring 1 is located at a distance c = 2a from the center of
the other two rings. We know that the total field resulting from these three rings at height y = -c is
zero, and we also know that the load of rings 1 and 2 is the same, positive and equal to q, and the
load of ring 3 is twice q and negative. Calculate the ratio b to a.
