The direction of magnetic field lines in a region outside the bar magnet is ______

As we know magnetic field lines always form closed loop. Inside the magnet the direction of magnetic field lines is from South Pole of the magnet to the North Pole of the magnet. But when the magnetic field lines come out of the North Pole, they have to form a closed loop, so they turn in outside region to go back to the South Pole. Hence, that is why direction of magnetic field lines in a region outside the bar magnet from the N pole towards the S pole of a magnet.
