Superconducting wires are electrical wires made of superconductive material. The superconductive properties are strongly dependent on the purity of the niobium metal. The appearance of superconductivity is associated with a phase transition, so there are superconductive states. The current persisted due to the superconductive state of the conductive medium. The superconductive transition temperature can be maximized by varying the dopant concentration. Today, high-end measurement systems use a superconductive magnet. Further purification is necessary to reach the grade for superconductive alloys. Both may display dissipationless superconductive currents at their edges near room temperature. By the early 1970s, this polymer was known to be superconductive at low temperatures. This summary makes an implicit assumption&colon; superconductive properties can be treated by mean field theory. It is also demonstrated in superconductive compounds such as CuNNi and ZnNNi. This phase is superconductive for color charge.
