6 Take a piece of Steel or Iron and magnetize it. Check it for its magnetization
Now demagnetize it and check it for its demagnetization. How did you do that?
Explain your experience with your observations. Draw the diagrams if necessary

Explanation:
Magnetizing
Place the magnet at one end of the piece of metal. The magnet must make as much contact with the metal as possible.
Place light pressure on the magnet and rub the metal in one direction only. Magnetization will take some time to accomplish so continue rubbing until the iron or steel attracts other pieces of metal.
Demagnetizing
Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible.
Rub the metal with the magnet in the opposite direction that you used to magnetize it. Continue rubbing until the metal no longer attracts other metal.
Wait out the magnetization, if desired. It is not necessary to demagnetize metal if time is not an issue because metal loses it magnetism over time.
