EVERYDAY SCIENCE

Detailed explanation-1: -This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth’s magnetic field direction and points north-south. Once you know where north is, you can figure out any other direction.

Detailed explanation-2: -When you use a compass to see which way is north, south, east, and west, you are really using a magnet. The little moving pointer in a compass is actually a small magnet! The needle lines up and points in a certain direction because Earth itself has magnetism and acts like a magnet too!

Detailed explanation-3: -The needle of a magnetic compass, itself being a magnet, can attract all kinds of magnetic materials. In the absence of external magnets, it always comes to rest in the North-South direction due to the Earth’s magnetic field.

Detailed explanation-4: -A compass is indeed a permanent magnet. It always possesses the property of pointing to magnetic north. This option is true. A compass has both a north pole and a south pole.
