An airplane wingspan can be approximated as a conducting rod of length 30 m. As the airplane flies due north, it is flying at a rate of 78 m/s through the Earth's magnetic field, which has a magnitude of 46 µT toward the north in a direction 57° below the horizontal plane. What is the Hall emf (in V) along the wingspan?

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.
