Answer» Thanks to all for the answers ????.
The path along which north pole moves in a\xa0magnetic field\xa0is called\xa0magnetic field line.
The magnetic field lines represented the magnetic field of magnetic field which shows the area of its influence.
The path along which north pole moves in a\xa0magnetic field\xa0is called\xa0magnetic lines\xa0of force or\xa0magnetic field line. They show the direction and strength of\xa0magnetic field. If\xa0magnetic field lines\xa0are very close to each other in a particular region,then the strength of\xa0magnetic field\xa0in that region,is very large.
