This document summarizes superconductors and their applications. It discusses the types of superconductors - type 1 which suddenly loses conductivity and exhibits the Meissner effect, and type 2 which gradually loses conductivity and does not exhibit the Meissner effect. It also outlines the key properties of superconductors like electrical resistance and the effect of impurities and pressure. Finally, it provides examples of applications of superconductors such as SQUIDs, cryotrons, levitating speakers, and Maglev trains.

• Types of superconductors
• Properties of superconductors
• Applications of super conductors
Objectives

3. Introduction
• 1911, Heike Kamerlingh Onnes
• Superconductor Conducts
electricity with no resistance
• Carry a current indefinitely
without losing any energy

4. Types of Superconductors
• Type 1 superconductor
 Suddenly losses its conductivity
Exhibits Meissner effect
• Type 2 superconductor
Gradually losses its conduvtivity
Does not exhibits Meissner effect

5. Graph showing the
conductivity of types of
superconductor
Type 1 and Type 2
superconductors when
placed in magnetic field

6. General Properties of Superconductor
• Electrical resistance
• Effect of impurities
• Effect of pressure and stress

7. Applications of Superconductor
• SQUID
• Cryotron
• Levitate superconducting
speakers
• Maglev train

8. SQUID
• SQUID-Superconducting
quantum interface device
• Magnetometer
• Most sensitive type of
detector

9. Cryotron
• Switch that operates using
superconductivity.
• It works on the principle that magnetic
field destroys the superconductivity.

10. Levitating Superconducting
Speakers
• Having a superconducting
element inside a transducer
• Power and data transmitted
wirelessly
• Freestanding loudspeakers
• Two constrasting designs are
there

11. Maglev Train
• Sound travelling through a fluid
• Effective magnetic poles to support magnet

12. Conclusion
• Superconductors
• Types of superconductor
• Properties of superconductor
• Application of superconductor

13. Any
Questions???
