### MAGNETISM

 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
the north pole of the magnet inside a compass is attracted to the south pole of Earth’s built-in magnet, which is why it always points north
 A true B false C Either A or B D None of the above
Explanation:

Detailed explanation-1: -Now the bar magnet’s south end is considered to be at the earth’s North Pole and north end at earth’s South Pole. 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: -Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).

Detailed explanation-3: -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.

Detailed explanation-4: -Believe it or not, that’s the way it is. Earth’s south magnetic pole is near Earth’s geographic north. Earth’s magnetic north pole is near Earth’s geographic south. That’s why the north pole of a compass points toward north because that’s where Earth’s south magnetic pole is located and they attract.

Detailed explanation-5: -The South Pole of the Earth’s magnet is in the geographical North because it attracts the North Pole of the suspended magnet and vice versa. Thus, there is a magnetic S-pole near the geographical North, and a magnetic N-pole near the geographical South.
