Used for supplying electrical power at times of emergency such as power outages, generators are important and useful appliances that helps continue events during an emergency power outage and it also saves businesses during these times of emergency. It is important to look at how generators create electricity and the important components that make up generators.
Electric generators convert mechanical energy that is obtained from an external source and exports it into electrical energy as an output. A critical thing to know about electrical generators is that it does not actually create the electrical energy that it uses. Rather, it uses the mechanical energy delivered to it to force the progression of electric charges that exist in the wire of its windings through an exterior electric circuit. The difference between mechanical and electrical energy is that mechanical energy is the sum of energy in a mechanical system and electrical energy is the presence and flow of an electrical charge.
In 1831 Michael Faraday discovered electromagnetic induction, the production of an electric current across a conductor moving through a magnetic field. Today's modern generator is founded on this concept of electromagnetic induction. This movement across the conductor creates a voltage difference, which in turn causes the electric charges to flow. This flow produces an electric current, which produces the electricity throughout the electric generator and makes the generator work properly.

As you can see in the video, the electric generator mechanical force into electrical current using magnetism.
