Where are superconductors used?

Answer 1

SuperConductors are electrical conductors having zero resistance. Superconductivity is referred as a "macroscopic quantum phenomenon". Superconductivity is reached at extreme cold temperature close to absolute zero. SuperConducting material will repel a magnetic field. normally a magnet hovering over a conductor will induce electrical currents in that conductor, this induced current is an exact mirror of the field that would have otherwise penetrated the superconducting material causing the magnet to be repulsed. This phenomenon is known as strong diamagnetism also referred as the "Meissner effect". The Meissner effect is so strong that a magnet can actually be levitated over a superconductive material. Superconductivity has so many application fields, and we have just mentioned one, "The levitation", which can make trains float over the rails. Superconducting magnets will significantly reduce power consumption in contradictory to traditional electro-magnets - CERN projects are a good example that uses huge superconductivity to accelerate particles. Another application field is biomagnetism, like MRI (magnetic resonance imaging) and another commercial application is the electrical generators wounded with superconductive wires which operates far more efficiently than the generators with copper wires.SuperConductivity has unlimited benefits in many other domains, we may also manufacture superconducting cables to transfer commercial electricity to the cities or integrate superconductivity concept into microchips.
