Magnetic Field Lines…

Magnetic Field Lines – The magnetic field lines are imaginary lines, tangent on these lines at a particular point gives the direction of magnetic field at that point.
(i) Magnetic field lines of a magnet from closed continuous loops,
(ii) Unlike electric field lines, magnetic field lines are directed from North to South outside a magnet and they run from South to North pole inside the magnet,
(iii) Two magnetic field lines cannot intersect each other.
