Step 1: Wrapping the copper wire

Take your copper wire and wrap it around something ( I used a weight). Once wrapped take off of object and using electrical tape secure around sides so it does not become uncoiled.

Step 2: Attaching the electrical wires to the copper wire

Take one of the two electrical wires and using the electrical tape attach to the side of the coiled copper wire, do the same thing with the other wire. Make sure the wires are secure.

Step 3: Making the magnet holder

Take your wooden rod and tape the magnet to the end. Or use a circular magnet (as shown in picture two) and tie it to a shoelace.

Step 4: Connecting to the light bulb

Take one of the two wires that is attached to the copper coil and attach it to the metal side of the light bulb. Take the other wire and attach to the little bulge on the bottom of the light bulb.

Step 5: Making the light

This is the trickiest step, don't get mad if it doesn't work right away. Take the wooden rod with the magnet on it and put inside the copper coil without it touching the sides and spin the rod until  the light starts to shine, this will take a while so just keep tweaking it until it starts to work. You can also twist the shoelace and do the same thing with it. The rod or shoelace can later be attached to a windmill to be powered by the wind. Good luck.

How much voltage does this experiment produce, and what kind of magnet is that? can you please tell it in a specific way so that I can buy those items specifically without any errors... Please... Reply Immediately, I will yous this experiment for my Science Investigatory Project, and I will assure you that you will become part of my acknowledgement...

what kind of magnet is it???
is it a normal Neodymium magnet or is it a diametrically magnetised Magnet???
how bright the light glow?any pics.

An AC bulb? Oh God! Impossible!

yes part of tweaking it includes getting a new bulb is part of it. I only used this bulb because it was easier to show people on.
