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

Steps to make a magnetic compass:

● Place the needle on a wooden table.


● Rub the magnet across its length without lifting it.


● Once the end point of needle is reached, lift the magnet and again rub it in the same direction.


● Remember not to change the direction and repeat the steps a dozen times.


● Now place the needle on the cork in a vessel containing water.


● The needle will move and align itself in the North-South direction.
