Electricity and magnetism
Hans Christian Oersted discover the electromagnetism
How magnetism produces electricity
Michael Faraday discover that a electromagnetism can produce energy
Electromagnetic generators
Using electromagnetism
The electric motor
Convert the eléctrical current into mechanical energy or movement
Electric motors are form by a coil wire placed between magnet
Electric generators
Dynamo transforms movement into electrical current
Dynamo is form by a magnet and a coil wire
Uses
Hydroelectric plants use water to movement
Wind turbines use wind energy
Thermal power plants use steam energy
