In this article we will discuss about:- 1. Introduction to Superconductors 2. Persistent Currents in Superconductors 3. Effect of Magnetic Fields 4. The Meissner Effect 5. Types 6. Josephson Effects 7. The London Equation 8. Squid. Introduction to Superconductors: The electrical resistivity of many metals and alloys drops suddenly to zero when their specimens are cooled to a sufficiently low [...]
In this article we will discuss about:- 1. BCS Theory of Superconductors 2. High-Temperature Superconductors 3. Applications. BCS Theory of Superconductors: For energy gap to occur there must be a mechanism whereby electrons in superconductors can lower their energy. Since the gap is very small (≈ 10-4 eV), such a mechanism is a weak attractive interaction, which is the resultant [...]

Superconducting Magnet. Introduction to Superconductivity: It was discovered in 1911 by Kamerlingh Onnes in Leiden when he observed that the electrical resistivity of mercury disappeared completely at temperature below approximate 4.2°K. A [...]
