GEOLOGY

Detailed explanation-1: -Answer: Solution: A compass has a magnetic needle that can rotate freely. When a compass is kept at a place, the magnetic needle aligns in a north-south direction.

Detailed explanation-2: -Magnetic compasses consist of a magnetized needle that is allowed to rotate so it lines up with Earth’s magnetic field. The ends point to what are known as magnetic north and magnetic south.

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.

Detailed explanation-5: -Because of the earth’s magnetic field. The magnetic field of the earth’s metallic core aligns its North toward the actual north. So a freely suspended magnet would align itself northwards towards the North of the earth’s magnet.
