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

1. A research group is investigating short-lived
radioactive isotopes. They need to design a
way to transport alpha-particles (helium nuclei)
from where they are made to a place where
they will collide with another material to
form an isotope. The
beam of alpha-particles (m=6.64×10-27kg,
q=3.2×10-19C) bends through a 90-degree
a region with a uniform magnetic field of
0.050 T (Figure 11.10). (a) In what direction should
applied? (b) How much time does it take the alpha-particles to traverse the
uniform magnetic field region?
