How Electricity Is Made Have you ever wondered where electricity comes from? Surprise!!! it comes from magnets!
How Electricity Is Made In the early 1800s, Michael Faraday discovered that if he moved a magnet through a loop of wire, the wire would become electrified.
How Electricity Is Made In 1882, Thomas Edison opened the first power plant in New York City: a big magnet rotates around a wire to produce an electric current.
How Electricity Is Made Today's power plants are bigger and controlled by computers.
How power plants make electricity? Coal is dug up and sent on trains and boats.
How power plants make electricity? The coal is burned to heat water to make steam.
How power plants make electricity? Inside the generator, the steam spins a big fan called a turbine.
How power plants make electricity? The
spinning
turbine
rotates
a
big magnet around a piece of wire & that motion creates a magnetic field that electrifies the wire.
How power plants make electricity? The electric current flows through the wire and is pushed out through highvoltage transformers.
More ways to make electricity: Some power plants burn natural gas instead of coal to make steam.
More ways to make electricity: A nuclear power plant splits apart uranium to release heat energy.
More ways to make electricity: A wind farm uses the wind to spin the blades of the turbine.
More ways to make electricity: A hydro power plant uses running or falling water to spin the turbine.
