Experiment

You can produce electricity!

You need:

• A slim cylinder (If you didn't get, make it yourself with paper or card board)
• Insulated copper thread 1 meter
• Powerful magnet (Wich can go through the cylinder)
• L.E.D. Bulb

You do:

Round the copper thread around the Cylinder in it's middle and fix the L.E.D. in it's two terminals like this:

Put the magnet into the cylinder and hold two mouths of it with your fingers and shake well.

Now the bulb lights.

Theory behind it is Electro Magnetic Induction.
