How Things Work: Superconductivity

Superconductive materials can achieve electrical resistance of 0 when cooled to a property temperature. As the superconductive material cools to its critical temperature, the Meissner effect causes an expulsion of a magnetic field. In this effect, when a magnetic field is applied to the superconductor, the material generates an opposing field. Research is currently being conducted on the development of room temperature superconductive materials.
