For a project you need to build a 40 cm-long solenoid. The strength of the magnetic field inside this solenoid has to be 5.4 mT. The design calls for a single layer of wire loops, wound as closely as possible. Two spools of wire are available: #18 gauge wire, which has a diameter of 1.02 mm and can carry a maximum current of 6 A and #26 gauge wire, with a diameter of 0.41 mm and a current rating of 1 A. Which wire would you chose to build this solenoid and why? What current will flow through your solenoid? Please justify your answers showing calculations/comparisons/etc.

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.
