GEOLOGY

Detailed explanation-1: -From the south magnetic pole to the north magnetic pole, this force has an effect on all magnetized objects, such as the needle of a compass. Under the effect of Earth’s magnetic field, the needle always points toward the north magnetic pole.

Detailed explanation-2: -Compass needle points towards north-south direction as the Earth has a geographical “magnetic nature” in that particular direction. So the compass aligns its needle with the magnet.

Detailed explanation-3: -We know that like poles repel and unlike poles attract. Thus, a freely suspended compass needle points to the earth’s magnetic North Pole getting attracted to the south end of the ‘imaginary’ bar magnet.

Detailed explanation-4: -The most important part on the compass is the magnetic needle. It swings around the compass as you move, but the red end will always point in the direction of north and the white (or sometimes black) end will always point in the direction of south.

Detailed explanation-5: -A2A: Compasses actually point north AND south in either hemispheres. We, in the northern hemisphere, just focus on the red, north seeking end being closer to that pole. The other, non-red end points south.
