The Little-Parks effect was discovered in in experiments with empty and thin -walled superconducting cylinders subjected. Superconductors, materials that have no resistance to the flow of electricity, are Meissner and Robert Ochsenfeld (above) discovered that a superconducting as strong diamagnetism and is today often referred to as the "Meissner effect".
The short distance super force field accounts for quantum phase transition at absolute zero, and provides the basic cause of superconductivity above absolute . Though superconductivity has been observed in many elements and compounds , it has not been observed for the best conductors like copper.
Some of the technological applications of superconductivity include: the production of sensitive magnetometers based on SQUIDs (superconducting quantum. 1. Power transmission cables. 2. Transformers. 3. Motors and generators. 4. Fault current limiters. 5. Superconducting magnets including MRI.

The Meissner effect (or Meissner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state. Hence the active exclusion of magnetic field must be considered to be an effect distinct from just zero resistance. A mixed state Meissner effect occurs with Type.
In Superconducting state, the superconducting material shows the zero electric resistance (infinite conductivity). When the sample of a superconducting material is cooled below its critical temperature/transition temperature, its resistance reduces suddenly to zero. Most of the physical properties of superconductors vary from material to material, such as the heat.
