Imagine materials that can carry an electric current with absolutely no resistance or bring the flow of a current to a stop. These materials do exist; they are called: superconductors. Materials that make good superconductors are materials that are copper-based, iron-based, and “heavy fermion compounds.” Superconductivity is achieved when contact between electrons causing antiferromagnetic order (a form of magnetism identified by an antiparallel arrangement of neighboring electron spinning in a crystal formation) can be kept while the actual order itself is prevented.
