Abstract. The aim of this article is to provide a general information about superconductors. Superconductivity is the weird phenomenon of zero electrical resistance that occurs when some materials are cooled below a critical temperature. To get cold enough liquid helium or nitrogen (often as low as -250 °C or -480 F) are used. This article primarily focuses on the history, the invention and the properties and the areas of usage of superconductors. The phenomena of superconductivity was first observed by Heike Kamerlingh Onnes in 1908 in Netherlands. Experimental physicists are now trying to find superconductors at room temperature. This article also intends to arouse curiosity among physics students
