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.

Question

Q7. If you were to move the north pole of a bar magnet into the front of your coil, what
is the direction of the induced current when viewed from the front? To reach your
conclusion, answer each of the following (see next page):
Motion of the magnet as viewed
from above.
The arrows by the magnet
indicate the direction in which
the magnet moves, not
necessarily the direction of B.
a) Is the flux within the coil increasing, decreasing, or remaining constant? Explain
in the space below.
b) Viewing the coil “from the front", what is the direction of Bo within the coil?
Done as an example to clarify
perspective. "From the front"
means looking into the coil.
(X) (since B lines point away from "N")
c) Viewing the coil “from the front", what is the direction Bind within the coil?
d) What is the direction of Iind in the coil, when viewed from the front?
