What is Electricity?
• The flow of electrons in usually in metals
• Metals are good electrical conductors because of the way the share electrons, there are “Free electrons” that can move through out the metal.
Electromagnetism
• If you run electricity through a wire
you will generate a magnetic field
• If you move a magnet near a wire, you will generate an electric current
Generators
• This generator is spinning a coil of wire inside of a magnet
• This generator moves a magnet near a coil of copper wire to generate a current

Power Plants
• Most power plants burn something
• to generate steam
• which is used to turn a turbine
• Which generates electricity
A motor is a generator
• You can either use electricity to run a motor….
• Or you can use mechanical energy to generate an electrical current.
• Just depends on what is driving it…
