according to magnetism, unlike poles must attract but why the compass needle shows the same direction as the earth's poles? According to the properties, it must show N for South pile and viseversa why is this so?
Answers
Answer:
A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
Answer:
A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth's built-in magnet. ... Since unlike poles attract, the thing your compass is being attracted to must be a magnetic south pole.
