A motional EMF system consists of a conductive bar that can freely slide across bare wires in which it is in contact with its ends. The resistance of the system is constant at 27.3 ohms. A constant force of 2.3 N is applied to the bar, making it slide across the wires at a constant rate of 5.5 m/s. What is the induced current in this system?

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.
