A dynamo has two main components: stationary magnets called stators, which create a powerful magnetic field, and a moving magnet called a rotor that rotates within the magnetic field. The moving rotor cuts through the flux lines of the magnetic field and this movement creates electricity.
The rotating movement of the rotor within the dynamo generates electricity by pushing the electrically charged particles within the magnetic field against one another. The magnets within a dynamo is made with a copper material that is wrapped around iron called a solenoid, which is a more powerful than a magnetite or a permanent magnet. The rotating motion of the rotor may be powered by falling water, wind and steam or gas turbines.
