What is the Direction of a line of flux

The direction of a line of flux is from the north pole to the south pole on the exterior of the magnet and is then supposed to continue by the magnet back to the point at which it emerged at the north pole. Therefore such lines of flux always form complete closed loops or paths; they never intersect and always have a exact direction. The laws of magnetic attraction and repulsion can be demonstrated by using two bar magnets.
