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.

You are assigned the job of building a very sensitive magnetic scale. Objects are hung from a horizontal rod through which an electric current is directed from left to right. The rod is loosely attached to a pair of vertical rails that allow it to slide up and down with almost no resistance. The entire scale is placed in an external magnetic field, and the current is adjusted until the rod and object levitate, balancing the downward gravitational force with an upward magnetic force. B? 1. In which direction must the external magnetic field point in order for your scale to work? 2. What current is needed to balance the scale if the combined mass of the rod and object is 1 kg, the length of the wire is 1 meter, and the magnitude of the external magnetic field is 0.1 Tesla?
