👉 In physics, a material or system that exhibits superconductivity is one where the magnetic moment of its electrons can be so high that it becomes infinite. This property has been observed in materials such as copper and nickel alloys, but also in certain types of ferromagnetic materials like iron and cobalt. Superconductive systems are typically composed of a conductor (like metals) surrounded by an insulator (like semiconductors). The superconducting properties of the material can be enhanced through various
