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.

7. How would I solve this?

In the velocity selector, if the magnetic field has a magnitude of
2 x 10-3 T, what should be the magnitude of the electric field (in
V/m) if the emerging particles are to have a speed of 10' m/s?
Answer:

y
E
Here, a positively charged particle q is traveling in the +y direction
with velocity i through a velocity selector where there is an electric
field directed towards the right (+x-direction). It then enters a
region (shaded) where there is a magnetic field of magnitude 1 Tesla.
