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.

Expert Solution

Step 1

Standard expression for the magnetic force (F) experience by the wire of length (L) kept in an external magnetic field (B) is,

$F = I \times L \times B$

Here,

I denotes the current flow through the wire.

F is the magnetic force such that F is acting in the direction perpendicular to plane of I and B.
