Properties of superconductors

• electrical resistance no longer measurable below a critical temperature
• above the critical temperature the superconductivity disappears
• stronger magnetic fields destroy the superconductivity
• a critical current strength destroys the superconductivity

Leon Neil COOPER describes superconductivity as the pair formation of two electrons at low temperatures.

Cooper pairs can move almost unhindered through a conductor under limited boundary conditions (temperature, current density, external magnetic field).
