  yes sir i have watched the videos...
  but my question is placing a super conductor in the middle of a bar magnet in the way that flux dont flow from N-S. does the flux continuesly comes out? if it goes to earths magnetic field, what happens is we close the N-pole with a super conductor...
  THANK YOU

  Flux will flow around it. What will happen if the whole earth is enclosed in a hollow sphere of magnetic shielding MU metal?
  The pole is not a single point. The field will go around in a radiating outward in the space below the superconductor.

  sorry for my bad English SIR....
  what if the magnet is closed by an superconductor.

  A bar magnet is just an assembly of millions of aligned magnetic elements. A magnetic line of force has meaning only when both ends exist.
  
  I am not sure about the hypothetical situation that you have illustrated.
  
  What is most likely to happen is that the exposed portion of the bar magnet will behave like a shorter magnet with the Noth pole located at the exit from the shield. The field lines will come to that point from the exposed South pole.
  Interestingly the end away from the North pole inside the enclosure may become the South pole of the portion of the bar inside with field lines between these two poles.
