Detailed explanation-1: -A compass needle will point to the direction of the Magnetic North Pole. But this doesn’t mean that a compass always points to the Geographic North Pole. This difference is magnetic inclination. The Earth’s magnetic north is changing every day because of the hot, liquid metal that surrounds the inner core.
Detailed explanation-2: -Magnetic Declination Varies Considerably Across The United States. The magnetic needle in a compass is attracted by the magnetism of the Earth, and therefore always points to the constantly shifting Magnetic North Pole. The Geographic North Pole is static and is located about 1200 miles north of the Magnetic Pole.
Detailed explanation-3: -The magnetic north and south poles of the earth are different from its geographical north and south poles.
