Key Concepts

Magnetic Flux Expulsion

Magnetic flux expulsion is the core characteristic of the Meissner effect, where a superconducting material actively expels magnetic fields from its interior as it transitions into the superconducting state. This behavior distinguishes superconductors from perfect conductors and highlights a fundamental quantum mechanical aspect of the superconducting phase.

Superconductivity

Superconductivity is a state of matter in which a material exhibits zero electrical resistance below a certain critical temperature. This phenomenon arises from the formation of Cooper pairs—bound pairs of electrons that move through the lattice without scattering—which underpins many of the unique electromagnetic properties observed in these materials.
