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.

A person grasps the ends of an electrically conducting copper wire in each hand. The wire has a cross-sectional area of 4.0x106 m² and its surface is not insulated. If the person's hands are wet, the resistance of the possible electrical pathway from one hand, up the arm, across the chest and down into the other hand is about 1 kQ.
