Conductors, like copper and early(a) metals, have very low resistance, and superconductors, comprised of certain metals such as mercury and ceramics such as lanthanum-barium-copper-oxide, have no resistance. protection is an obstacle in the flow of electricity. Superconductors also have powerful diamagnetism. In other words, they are repelled by magnetic fields. callable to these special characteristics of superconductors, no electrical energy is lost while flowing and since magnetic levitation above a superconductor is possible. This principl...If you want to repel a full essay, order it on our website: Ordercustompaper.com
