A superconductor is a material that achieves superconductivity, which is a state of matter that has no electrical resistance and does not allow magnetic fields to penetrate. An electric current in a superconductor can persist indefinitely. Superconductivity can only typically be achieved at very cold temperatures. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSvjx3jlhsXma8HSCTnQqrBuNItz-Kmba-8Cg&s
