Question

Suggest an activity to prepare a magnetic compass by using an iron needle and a bar magnet.

Answer 1

Using the approach below, you can make a magnetic compass.

1. On a wooden table, place one needle.

2. Move a magnet along the length of the needle without raising it.

3. When you reach the needle's endpoint, raise the magnet and rub it in the same way again.

4. Keep going in the same direction as before and repeat the steps.

5. Now, in a water-filled container, set the needle on the cork.

6. The needle will change and position itself in the "North-South" way.
