Superconductor

  1. 1. ‘SUPERCONDUCTOR’ A presentation by Sabyasachi Chatterjee, Sandeep Biswas, Sandip Ghosh Department-Electrical Engineering Semester-5th
  2. 2. What is ‘superconductivity’?
  3. 3. History
  4. 4. • Superconductivity was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8,1911.
  5. 5. How it works
  6. 6. How it works
  7. 7. Difference between normal conductor & superconductor
  8. 8. Expulsion of magnetic field by superconductor
  9. 9. Classification
  10. 10. Classification based on 1. Critical temperature
  11. 11. Classification based on 1. Critical temperature 2. Response to magnetic field
  12. 12. Classification based on critical temperature
  13. 13. Classification based on critical temperature 1. High temperature superconductor
  14. 14. Classification based on critical temperature 1. High temperature superconductor 2. Low temperature superconductor
  15. 15. Classification based on response to magnetic field
