SIDE A A DYNAMO is a machine which converts movement into electrical energy. A GENERATOR is a giant dynamo. A dynamo needs a source of energy to spin or turn it. Handle turns the shaft coil of wire which turns when the shaft turns The secret inside magnet Inside every dynamo is a coil of wire and strong magnets. Michael Faraday, in 1831, discovered that if you spin a coil of copper wire between magnets you could get a flow of electricity. The more loops of wire you have, the more electricity is generated. By turning the handle on the dynamo, you turn the coil between the two magnets. This motion causes an electric current to flow through the coil of wire. electrical contacts Electricity flows along the wire and lights the bulb Renewable energy machines Renewable energy technology uses TURBINES to turn GEARS which then turn a SHAFT inside a GENERATOR. The turning shaft spins a huge coil of wire past giant magnets and generates ELECTRICITY. Gears Turbines Shaft Electricity See over for information on electric motors Generator (dynamo) SIDE B An electric motor is a dynamo in reverse. First Electric Motor The first, very simple, electric motor was made by Michael Faraday in 1821. He showed that a single wire, suspended between magnets would revolve when a current was passed through it. Electric Motor Coil of wire which feels a force and turns when electricity flows through it motor spinning magnet electrical contacts Electricity flows along the wire from the battery battery RENEWABLE ENERGY TOOLKIT FOR PRIMARY SCHOOLS
