Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance . This produces interesting and potentially useful effects. For a material to behave as a superconductor, low temperatures are required.

Examples include high-speed magnetic-levitation trains, magnetic-resonance-imaging (MRI) equipment, ultra-high-speed computer chips, high-capacity digital memory chips, alternative energy storage systems, radio-frequency filters
