LET US MAKE MAGNETS
Take a nail / a piece of Iron and place it on a table. Now take a bar magnet and place one of its poles near one edge of the nail/piece of Iron and rub from one end to another end without changing the direction of the pole of the magnet. Repeat the process for 30 to 40 times.
Bring a pin or some iron filings near the nail/piece of Iron to check whether it has become a magnet. Does the nail/piece of iron attract the pin/iron filings? If not, continue the same process for some more time.
