Inside a magnet, the direction of magnetic field lines is from its south pole to its north pole, forming closed curves.
Inside a magnet, the direction of the magnetic field lines runs from the magnet’s north pole to its south pole. Magnetic field lines conventionally represent the hypothetical path a small north magnetic pole would follow within the magnetic field. Therefore, inside a magnet, the magnetic field lines form closed loops, emerging from the north pole and entering the south pole.
This directionality is based on the convention that magnetic field lines do not have an independent existence but are used to visualize the magnetic field’s influence. The north pole of a magnet is defined as the pole that would be attracted to the Earth’s geographic north pole when freely suspended, and the south pole is the opposite. The field lines’ orientation reflects the tendency of magnetic poles to attract each other, following the basic principles of magnetic interactions.
