"They are electricity conductors without any resistance. The property of superconductivity is achieved only with very cold temperatures and no magnetic field can exist within a superconductor. Power utilities, electronics company also military transportation have benefits with the discovery of this materials. Type I superconductors are conducting in room temperature but when cooled below critical temperature, the molecular motion reduces. Type II superconductors take time for transition when compared to Type I. Properties displayed by these materials are infinite conductivity, Meissner effect, transition temperature, Josephson currents, persistent currents etc. Applications include MRI scanners, memory elements, generators, particle accelerators, electric motors and so on. Examples of elements having this property are aluminium, mercury, zinc, cadmium and lead. Some compounds and alloys also exhibit superconductivity. Information about superconductors is explained in detail in powerpoint presentation."
