How to Create Electricity

Primary sources of energy such as coal, nuclear and solar energy are converted into electricity. Electricity is the byproduct of that renewable or non-renewable energy conversion. Think of it as an energy carrier. Children often create simple energy conversion experiments in school to generate electricity by using potatoes and conductive wire to adjust the flow of electrons between atoms. Or they shock each other by rubbing their feet on the carpet and touching a person or thing to discharge the built-up static electricity. Adults can create electricity by using magnetism.

Difficulty: Moderate

Instructions

Things You'll Need:

• Magnet
• Wire
• Axle
• Ammeter
• Glue

1. 1. Glue a magnet to an axle.

2. 2. Turn the axle to create spin. The spinning magnet creates a magnetic field. You are using kinetic energy to spin the magnet which can be converted into electrical energy. The first law of thermodynamics reveals that energy (matter) cannot be created or destroyed (only converted). Whatever energy is created in your spinning magnetic field will be equal or less than the electrical energy produced by its spin.

3. 3. Induce an electric current by wrapping a length of wire around the magnet, but not attached to it. The wire should create a stationary loop around the magnet rotating in its center. The more you wrap the wire around the magnet, the more current is induced when you give the wire and magnet a spin. Verify by measuring the current with an ammeter. The ammeter measures current by touching its leads to either side of the wire.
