A metal is said to be a superconductor if it has some resistance at room temperature, but when it is brought down to a critical temperature; i.e. to a very low temperature such as 20 K, it loses its resistivity completely. Also, a superconductor expels out any magnetic field inside of it that it had at room temperature, and is not affected by any further field applied to it at its cooler temperature.
