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.

Which image represents the direction of the electric field that completes a velocity-selector arrangement?

Problem 7: The Lorentz force is the sum of the electric and magnetic forces acting upon a particle
with charge
9 and velocity
F = qË+qvxB
A velocity selector is a special arrangement of non-zero electric and magnetic fields that will allow
charged particles with a specified velocity to pass undeflected because the Lorentz force they
experience is zero. Charged particles with other velocities are turned aside. This is achieved as
follows:
• The three relevant vectors, v, Ē, and B are mutually perpendicular.
• The magnitudes of the vectors are chosen such that the magnitudes of the electric and magnetic
forces have equal magnitudes, or, equivalently, E = vB.
• The directions of the electric and magnetic fields are chosen such that the electric and magnetic
forces are oppositely directed.
The diagram to the right represents the directions of a uniform magnetic field and the velocity vector.
The charge of the particle is explicitly indicated as
+q> 0 or
-9 <0.
