A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.

Answer: Geographic north (True north) also known as North Pole. Geographic north is the the point of intersection of Earth's axis of rotation and surface. Magnetic north is the direction towards the north magnetic pole, which is a wandering point (changing with time) where the Earth's magnetic field goes vertically down into the planet. The geographic north and magnetic north is separated from each other by 11.5 degrees. Kindly refer to the attached figures.
