Answer:

14 No, the lines of magnetic field from a bar magnet form closed lines. The field direction is taken to be outward from the North pole and in to the South pole of the same bar magnet.

15 When two distince magnets are brought closer, depending upon which poles of the magnet are closer, the magnetic fields either attract (in which case, the magnetic come closer) or repel ( in this case, the magnetic lines move far apart) but the magnetic lines never intersect because if two lines intersect.
