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?

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 ?

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 : 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 . 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 ? :

Take a long rubber band and cut it at one point . At one of its ends tie a clean washed stone or a 50g weight as shown in figure Now hold the other end of the rubber band and make a mark there . Keep the stone hanging in air and measure the length of the rubber band from the stone to the mark made earlier . now take water in a pot and hold the rubber band at such a height that the stone sinks in it . again measure the length of the rubber band up to the mark . : What is observed ?:

Rub one end of a glass rod against a silk cloth. Due to the rubbing a small charge will get transferred from one object to the other. As a result both the objects will become somewhat charged. Suspend this rod freely in air with the help of a thread. Now charge another glass rod in the same manner and bring it near the suspended tod. What do you see?
