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.

A bar magnet has two poles -- a north pole and a south pole. If the bar was cut in half each half would be either north or south. each half would have its own north pole and south pole. each half couldn't be attracted to the other half. each half would lose its magnetism. The total resistance in a circuit containing resistors connected in series is given by the sum of the individual resistances the sum of the currents the sum of the inverses of the individual resistances the sum of the voltages
