Final answer:
Magnetic field lines for a bar magnet point away from the north pole and toward the south pole, following the direction a north pole of a compass needle would point when placed near the magnet.
Step-by-step explanation:
If you drew magnetic field lines for a bar magnet, the arrows on the magnetic field lines would point away from the north pole of the magnet and toward the south pole. This is because magnetic field lines are defined by the direction in which the north pole of a compass needle points. As explained in various figures, when placing a compass near a bar magnet, the north pole of the compass (which is actually a magnetic south pole) is repelled by the bar magnet's north pole and attracted to the bar magnet's south pole. Hence, this indicates the direction of the magnetic field lines from north to south outside the magnet.
Inside a bar magnet, these magnetic field lines form continuous closed loops, eventually connecting the south pole back to the north pole within the magnet. Therefore, the correct statement about the direction of magnetic field lines is that they point away from the north pole and toward the south pole of a bar magnet.
