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.

1a. Select the best answer and explain why each of the wrong answers are incorrect. Which of the following configurations would allow for a maximum induced current through a 1m segment of wire in the presence of a changing magnetic field? (a) a single circular loop (b) a single square loop (c) a 5-turn circular loop (d) a 5-turn square loop 2a. An electric generator utilizes the principle of magnetic induction to generate a DC current. To do this, a wire loop is rotated relative to a hard magnet so that the magnetic flux through the loop is constantly changing (see the diagram below). However, this process is slightly flawed to produce a constant DC current that always moves in the same direction. Explain why this is flawed.
