GEOLOGY

Detailed explanation-1: -Magnetic north is determined by the direction of a compass points. So, the magnetic north and south poles of the earth are different from its geographical north and south poles.

Detailed explanation-2: -Earth’s geographic and magnetic poles are not exactly aligned because they arise from different mechanisms. Earth’s magnetic field is caused by circulating currents of liquid iron in the outer core. Furthermore, earth’s magnetic poles are constantly changing location relative to earth’s geographic poles.

Detailed explanation-3: -Magnetic north is the direction towards the north magnetic pole, which is a wandering point where the Earth’s magnetic field goes vertically down into the planet. The north magnetic pole is currently about 400km south of the north geographic pole, but can move to about 1, 000km away.
