Mag-Lev trains can reach high speeds in part by minimizing the friction associated with moving over the ground. The strong magnetic fields necessary to lift a train are generated by superconducting electromagnetic coils. An engineer believes that each of the solenoids used in the train track needs to generate a field no less than 4.0 Teslas using a current of 6.5*102 A. If the coil can be no longer than 25 cm in length, how many windings would it need?

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.
