GEOLOGY

Detailed explanation-1: -When a bar magnet is suspended in the Earth’s magnetic field, orients itself in a north-south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. The south-seeking pole, or any pole similar to it, is called a south magnetic pole.

Detailed explanation-2: -Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole.

Detailed explanation-3: -Whereas the south pole of the magnet is aligning itself with the magnetic north of Earth. So that is the reason we call them as north pole and south pole is because they align or they show us the direction of the our geographical north and south of Earth.
