12.  The magnitude of a magnetic field that passes through a stationary wire loop (consists of 50 turns and has an area of 0.15 m2) varies according to the plot shown above.  On the other hand, the direction of the field is kept the same all through out. Note that the field changes within three equal time intervals (0s - 3s, 3s - 6s, 6s - 9s) and that the magnetic field is oriented parallel to the normal of the loop.  (a) For each interval, determine the induced emf.

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.
