One of the main areas of focus in condensed matter physics over the past several years has been research on high-temperature superconductors and their physical characteristics. One of a metal’s most crucial characteristics is its electrical resistivity, and scientists were especially curious about how this value varied with temperature. Because superconducting wires can carry enormous electrical currents without heating up or losing energy, superconductor-based electromagnets are incredibly strong. The current state of technology is predicted to alter with the development of a superconductor that runs at room temperature. Compared to existing technologies, a superconducting power grid would save a great deal of energy because it would not waste energy owing to very little resistance. High magnetic fields can be produced by high-temperature superconductors, which are advantageous for applications in medicine, such as magnetic resonance imaging (MRI) equipment. Superconductors are used in levitating trains, very accurate electromagnets, lighter and smaller engines, generators, transformers, and SQUIDs.
