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 square current loop of 26.2 A is inscribed within a circular current loop A in the plane of the page. What must the current in the circular loop be such that the net magnetic field at the center of the system is zero if the radius of the circular loop is 0.09m? Assume that the magnetic felds produced by the loops are in opposing directions at the center or the system.
Let's add a battery to the usual sliding rod set-up: B is uniform sliding rod The whole circuit is lying horizontally on the ground. The rod starts at rest, and accelerates due to the magnetic force on it. After a while, you discover that its velocity stops changing. What is the value of the final speed (in m/s) of the rod? The magnetic field is 8.27T, the battery has an emf of 6.03V, the resistor is 4.54 ohm, and the distance between the two parallel rails is 4.56m. Hint: Pay attention to the magnitude of the magnetic force on the sliding rod. Rewrite the circuit in the usual way: by replacing the sliding rod with a battery of emf=BvL; then apply Kirchhoff's loop rule.
