2. • Brief idea on superconductor
• 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???
