4. Describe an experiment to show that a freely suspended magnet always aligns in the
north-south direction.​

Answer 1

3. The needle is a small magnet that aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north, you can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose.

4.A bar magnet when suspended freely with a silk thread comes to rest along the North-South direction of the Earth. Even if the magnet is turned to some other direction it will always show the North-South direction of the Earth.
