Description

This lecture covers the analysis of the magnetic field around a coaxial cable, focusing on the principles of current circulation and magnetic potential. Starting with the basic concept of coaxial cables having two concentric cylindrical conductors, the instructor explains how the magnetic field varies with distance from the conductors. By applying the principle of circulation, the lecture delves into the calculation of magnetic potential and density of current at different distances within the cable. The discussion progresses to illustrate how the magnetic field strength changes between the inner and outer conductors, highlighting the cable's ability to confine radiation and resist external electromagnetic disturbances. The lecture concludes by emphasizing the practical advantages of using a coaxial cable in terms of signal transmission and interference immunity.
