Hint: A magnetic compass does not point at the normal geographic North Pole. A magnetic compass refers to the magnetic poles of our planet, which are not similar to the geographic poles. Therefore, the earth’s magnetic field line extends from the geographic hemisphere of the south to the geographic hemisphere of the north.
Complete step-by-step answer:
The magnetic pole at the geographic north pole of the planet is simply the magnetic pole of the south. If it comes to magnets, they draw opposites. This means that the north end of the magnet in the compass is drawn to the south magnetic pole, which sits close to the north geographic pole. Magnetic field lines beyond the permanent magnet often extend from the magnetic pole of the north to the magnetic pole of the south. The magnetic field lines of the earth, then, extend from the southern hemisphere to the northern hemisphere.
Earth's magnetic poles represent the central location of the area where the lines of the magnetic fields begin and stop. Geographical and magnetic poles of the Planet are not precisely compatible since they originate from various processes. The magnetic field of Earth is caused by the movement of molten iron in the outer core. Furthermore, the magnetic poles of the planet are continuously shifting their positions relative to the physical poles of the earth.
'Magnetic North' is a place; so-called to differentiate it from True North-it has little to do with its magnetic polarity. The magnetic polarity at this position is south-which is why it draws the north-facing pole of a compass needle or magnet.
Hence, option A is correct.
Note: Here we should note that magnetic south is different from magnetic polarity. If magnetic polarity had been mentioned in the question then the answer would have been different.
