|
Because the magnet inside the compass orients itself along north/south lines.
|
|
|
Because the magnet inside the compass is oriented on an east/west access.
|
|
|
Because the person holding a compass must always face north.
|
|
|
Not all compasses point north.

Detailed explanation-1: -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-2: -The magnetic field is a zone where the force is active along imaginary lines. 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-3: -This happens because the Earth behaves like a huge magnet. The magnetic north pole of the Earth is near its geographic south pole. Due to this, a freely suspended magnet aligns, so that its north pole points towards the geographic north pole. In other words, the magnet aligns in the North-South direction.
Detailed explanation-4: -A freely suspended magnet points in the north-south direction because the earth behaves as a magnet with its south pole in the geographical north and the north pole in the geographical south. Was this answer helpful?
Detailed explanation-5: -The direction of the magnetic field is taken to be the direction in which a north pole of the compass needle moves inside it. Therefore it is taken by convention that the field lines emerge from north pole and merge at the south pole.
