These are imaginary lines along which the iron fillings would arrange themselves in circular orbits due to the force acting on them.

The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. They show the direction and strength of the magnetic field. If magnetic field lines are very close to each other in a particular region, then the strength of the magnetic field in that region is very large. A magnetic field line is an imaginary curve along which a free unit north pole tends to move. Magnetic field lines always start from north pole and end on the south pole. The tangent to the magnetic field lines at any point gives the direction of the magnetic field at that point.
