The electric motor - An electric motor is a device where you input current to a loop (or stack of loops) and get out rotational motion. Attatched picture depicts the behavior of a current loop in a magnetic field: assume the magnetic field at the location of the loop is upwards. Each of the picture shows the loop at different orientations, with currents indicated by x&o. 1. If I wanted to make an electric motor out of the device (would spin continuously), what would be the flaw in the design? 2. How might this motor be addressing the flaw identified in Q1?

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.
