By studying how electric motors and generators work, you will familiarize yourself with fundamental magnetism and its connection to electricity in the context of this topic.
1. Stator - The main function of the stator is to provide magnetic fields where the coil spins. A stator includes two magnets with opposite polarity facing each other. These magnets are located to fit in the region.mp4Learn and have fun with simple electric motors and generators.

generator
A generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output.
It is attributed to Michael Faraday’s principle of ELECTROMAGNETIC INDUCTION, which states that when a conductor moves in a magnetic field, electrical charges can be created and directed to create a flow of current.
At its most basic, an electrical generator is nothing more than an electromagnet – moving wire near a magnet to direct the flow of electricity.
It is important to understand that a generator does not actually “create” electrical energy, but rather uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.
This flow of electric charges constitutes the output electric current supplied by the generator.
How water, wind, and steam make electricity through generator?
water
water
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of the falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
wind
wind
The wind turns the blades of the windmill, known as the turbine, which, in turn, spins the shaft that turns the coil inside the magnet, known as the generator, and it produces the electricity.
fossil fuel/ steam
fossil fuel/ steam
Oil is burned to heat water which makes steam. Steam moves the turbine blades that turn a shaft inside the generator. The shaft spins the coil of wire inside a magnet in the generator that produces a current of electricity.
What are the main components of a DC generator?
A DC generator is an electrical machine which converts mechanical energy into direct current electricity.
electric motor
electric motor
Anything that changes electricity into motion, meaning electrical energy into mechanical energy is called an electric motor.

HANS CHRISTIAN ØRSTED
Danish physicist HANS CHRISTIAN ØRSTED began a new scientific era when he discovered that electricity and magnetism are linked. He showed by experiment that an electric current flowing through a wire could move a nearby magnet.
The discovery of ELECTROMAGNETISM set the stage for the eventual development of our modern technology-based world.
How do Electric Motors work?
How do Electric Motors work?
Motors operate on the basis of electromagnetism, where electricity runs through a wire and creates a magnetic field around a rod. One end of the rod has a north magnetic pole, and the other has a south magnetic pole. Opposite poles attract one another, and when surrounded by other magnets, the rod will rotate due to the attractive and repulsive forces.
