How To Make An Electromagnet | Awesome Physics Project

Today i was studying about flux change and electromagnetism in which, I came to know that there is a simple project related to this. so I checked that was a to make a electromagnet. That was very easy and I made it in 5 minutes .it is really awesome you can check it at below in video. I didn't give much of turns there for it was not too strong but it was a magnet.

Requirements:-
* 9v Battery
* Dc Switch
* Copper Wire (Coil)
* Match Box
* Ruler ( Your Choice )
* 2x Nuts ( One Needed )
* Glue Gun 
* Soldering Iron
* Some Metal Things ( I have used small nails )

Procedure:-
1......First I attach the switch on the side of 9v battery. I bend one side of the switch so it touch the positive terminal of battery.
2.....In next step I attach the 9v battery with the ruler with the help of glue.
3.....Then I took the coil and around the bolts I give it some turns. Around 27-30 turns.( More Turns Stronger The Magnet Will Be )
4.....Then I removed the isolation from the end side of copper wire. For this I used a fire there are many way you can  remove that isolation if you don't want to use it.
5......At first I attach the one end of copper wire with negative terminal of battery by Soldering Iron. Then I attach the the switch with the positive terminal. And at last I connected the other end of copper wire with the 2nd end of switch.
6......Circuit Completed.....After Turning 'On' the switch it worked. I have demo video Below check it and you will understand much more.  

Some Common Problems:
If didn't worked try to increase turns and voltage.


GOOD LUCK

I Know My Videos Are Not Good Bear Please Bear It I Am Trying My Best To It Make Perfect.
