In a hydroelectric plant, falling water exerts a torque on a water wheel, causing it to spin. The water wheel's shaft is attached to a conductive loop of wire suspended inside an external magnetic field, which rotates with the water wheel (see the image attached). Unlike the one-direction direct currents (DC), the electric currents generated by the spinning water wheel will be an alternating (AC) current that periodically reverses direction.   Citing any relevant physical laws, explain (in detail) how the hydroelectric plant generates electricity and why the current will cycle through two opposing directions

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.
