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 \(2 \times 10^{-3}\) T, what should be the magnitude of the electric field (in V/m) if the emerging particles are to have a speed of \(10^7\) m/s?

**Answer:** [Input Field]

The diagram shows a positively charged particle \( q \) moving in the positive \( y \)-direction with velocity \( \vec{v} \). It is passing through a velocity selector, where an electric field \( \vec{E} \) is directed towards the right (in the \( +x \)-direction). The velocity selector ensures that only particles with a specific velocity pass through unaffected. After this, the particle enters a shaded region that contains a magnetic field with a magnitude of 1 Tesla.

In the graph:

- The grid represents the coordinate plane with axes \( x \) and \( y \).
- The path of the particle is shown as a black arrow moving upwards along the \( y \)-axis.
- The electric field \( \vec{E} \) is indicated by a horizontal arrow pointing to the right, in the \( +x \)-direction.
- The shaded area represents the region with the magnetic field.

This setup illustrates how charged particles behave under the influence of electric and magnetic fields, often used to separate particles of different velocities in experimental physics.
