Winding the Wire
Wind the wire on the nail. Each turn has to be close to the other. More the turns the more powerful the magnet. Leave a little length of wire before you start. And leave a little after you end.
Connecting the Source
Connect one end of the battery to one end of the wire. Then the other end to the other end. You can add a switch if you want.
The End
That's all. Use it to attract iron nails.
