Let’s try this :
Fix a powerful bar magnet to a stand as shown in the figure. Fix an iron bar at a short distance below the magnet. Take iron filings near the iron bar. What do you see ?

Let’s try this : Fix a bar magnet to a stand as shown in the figure. Let it become steady. Take another bar magnet near the hanging bar magnet. Observe what happens. Do the same again and again, exchanging the ends of a magnet. What do you see ?

Let’s try this : Take a bar magnet that can be cut with scissors or a knife. Take iron filings on a sheet of paper and place the magnet on it. Most of the iron filings will be seen to stick to its poles. Now cut the magnet into two pieces as shown in the picture and place those pieces on iron filings. Pick up each piece and observe. What do you find ?

Take the inside tray of a used up match box and place a small magnetic needle inside the tray . Now take a long connecting wire and wind it around the tray . Complete the electric circuit ny connecting in it , this wire , electric cell , plug key and a bulb as shown in the below figure .: Mark the position of the magnetic needle . take a bar magnet near to the magnetic needle .: What do you observe ? :

Let’s try this : Place some iron filings on a sheet of paper and pass a bar magnet by holding it in the centre. What do you see ?

Take the inside tray of a used up match box and place a small magnetic needle inside the tray . Now take a long connecting wire and wind it around the tray . Complete the electric circuit ny connecting in it , this wire , electric cell , plug key and a bulb as shown in the below figure .: Mark the position of the magnetic needle . take a bar magnet near to the magnetic needle . keep looking at the needle and close the plug key . the bulb will light up , and you will realize that the current has started flowing . does the magnetic needle change its position ? :

Let's try this : Take a needle or a nail. Place it steady on a table. Keep on rubbing a magnet over it from one end to the other. Do this 7-8 times. Now take a few pins near that needle/nail. What is seen?

Apparatus: Bars of stainless steel, aluminium and copper, a candle, a burner, pins, etc. : Procedure: Take stainless steel (or iron), copper and aluminium bars, each about 30 cm long and having the same shape. Apply wax spots with the help of candle at a distance of 2 cm from each other on all the three bars. Stick a pin in each of these spots so that it is upright. Now insert the ends of all three bars into a flame at the same time. for a while. What do you see? From which bar do the pins start falling first? Why?
