Please answer it in detailed solution. I have attached the formulas and references that we use. Consider an electron moving as part of the current in a metal wire. Electron moves with drift velocity which is typically v= 0.01 m/s. suppose there is a magnetic field of B=2.0 T perpendicular to the wire. The wire considered has an electric field of about 0.02 V/m. What is the ratio of Electric force to Magnetic force?

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.
