Science Project on “Magnetic Forces”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.
Magnetic Forces
Materials Required:
- A strong magnet
- Stapler pins
- Two glasses
- Two books
- A pencil
- A cylindrically shaped balloon
- A freezer
- A ruler
An invisible form of energy, magnetism can actually pass through air. But the question is – can magnetism also pass through water? What is the essence of water as ice? Would that affect magnetic forces?
To find out, fill a cylindrical shaped balloon with water. Remember that you should not blow any air into the balloon, but just fill it with the water that you shall be using for the experiment. Now take a pencil and tie your water-filled balloon to it. With the help of the glasses, place the pencil in such a manner that the balloon should hang. Place the two books on either side of the glasses, so that the balloon comes in between them. On one book, place a magnet and use the other book to hold a stapler pin.
Now, using the water-balloon as a barrier between the two books, start bringing the two objects – the magnet and the stapler pin close to each other, so that the magnetic force of the former can affect the pin. Once this happens, note the distance between the two.
Now carry the entire balloon and glass setup to the freezer, without disturbing the books or the magnet. Once the water in the balloon freezes, remove the setup and bring it back to its old position.
Now the stapler pin should be placed in the spot where it had earlier been attracted by the magnet. Please note whether magnet still attracts the pin through the ice barrier.
