Superconductivity is a second order electronic phase transition that occurs in certain materials when they are cooled below certain temperature. It is characterized by complete absence of electrical resistance. It also involves the complete expulsion of magnetic fields from the interior of the superconducting material below its critical temperatures. The mechanism of the superconductivity in high temperature superconductors remains a puzzle in physics as there is no consensus on the theory of superconductivity that satisfactorily describes these materials. Superconductivity has several useful applications such as generating high magnetic fields, magnetic levitation which hold a very promising future in transportation. In my presentation, I will be describing the theory that models superconductivity, types of superconductors and applications of superconductivity.
