Answer:

  • A substance which conduct electricity without resistance ,as it is colder than critical temperature.
  • At critical temperature electron moves freely through material.
  • Superconductivity destroys at high magnetic field.
  • At high magnetic field it restores is normal conducting state.
  • Examples of superconductor are as follow :
  1. Niobium
  2. Magnesiumdiboride
  3. Cuprates
  4. Aluminium
  5. Iron pnicitides
  6. Copper oxide
  • Superconductor are metallic so they have high critical field densities.
  • It is malleable
  • It has high critical current.
