Welcome to our blog Experimenters! In this blog we'll show you how you can make your very own permanent magnet in home using the items available in your home.
Normally we used to magnetize iron pieces such as needles, iron nails etc by rubbing them against a magnet. But the magnetic field produced by such magnets are weak and unstable. And also their magnetic property dosen't last long!
By using the technique mentioned in this blog, you would be able to make yourself a permanent magnet easily,within short interval of time.

1)Things required
So the things required for this experiment are -
1. a Solenoid
2. a battery (AA/AAA)
3. small iron piece such as a nail
2)What is a Solenoid?
You too can make a solenoid in home. All you need is a pen ( or a suitable non conducting cylindrical tube such as plastic pipe etc) and a copper coil. Wind the copper coil around the pen (empty) just as shown in the picture below...
Remember,more the number of turns of the coil around the pen ,stronger the magnetic field produced!
3)Conduction
Take the iron piece and insert it inside the solenoid. Connect the ends of the Solenoid coil to a 3V (or higher) AA/AAA battery for some time (approximately 15 - 20 seconds).
Remove the iron piece and check whether it is magnetized or not. Repeat the conduction process if the iron piece isn't magnetized until the iron piece acquires the magnetic property.
There you have made yourself a Permanent magnet!!. Enjoy with it. :D
You can watch this video where we conduct the experiment of magnetizing a needle here

If you wish to demagnetize the iron piece,insert it in opposite direction (with respect to how it was inserted during conduction in the beginning) into the solenoid. Connect the ends of the coil to the 2 terminals of the battery for some time. Your iron piece gets demagnetized!
Or
You can also demagnetize the magnet by heating it to high temperature (above Curie point) for some time, until it loses its magnetic property!
This video below shows you how to demagnetize a Permanent Magnet by heating it!
