As a diligent physics student, you carry out physics experiments at every opportunity. At this opportunity, you carry a 1.27 m long rod as you jog at 3.17 m/s, holding the rod perpendicular to your direction of motion. What is the magnitude ?B of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.301 mV across the rod? Express the answer in milliteslas.

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.
