Faraday created the first transformer in August 1831. A few months later he designed and made this simple piece of apparatus based on his ring, developing the first-ever electric generator.
Alternative name: Dynamo
Materials: Wire, cotton, iron, card, copper
Measurements: H: 280mm, W: 220mm, D: 40mm
This is Michael Faraday''s generator. This apparatusconsists of a tube of neutral material wound with a coil of wire, insulated in cotton, and a bar magnet.
Ten years afterFaradaycreated the electric motor he returned to his electrical research and discovered electromagnetic induction in August 1831. A few months later he successfully conducted an experiment using this apparatus and demonstrated the relationship between magnetism and motion.
Faraday connected his apparatus to a galvanometer (an instrument that detects electrical current) and discovered that when he passed the magnet back and forth through the coil of wire, which remained stationary, the needle of the galvanometer leapt into action registering a current flowing.
As the magnet moves the lines of magnetic force repeatedly intersect with the wire exciting the electrons in the wire and generating electrical current. So if you exchanged the galvanometer with a light bulb today you would see it light up.
Virtually all electric power is produced using Faraday''s principles, no matter whether the prime source of energy is coal, oil, gas, nuclear, hydro, or wind: all these fuels are used to drive a generator (or turbine) which generates the electrical current.

A power generator is a system that utilizes electromagnetic induction to generate utility from a mechanical engine. It functions similarly to a water pump by forcibly maneuvering a rotor round a stator, which creates an electrical field from an electromagnet. Power generators have come a long way and are necessary to maintain productivity in modern society.
Early generators used electrostatic principles to operate but today they use magnetism and electricity. Van de Graaff generators use a charge transmitted from an electrode of high voltage or by triboelectric charging in which specific elements are electronically charged when they come into contact with other elements. The Wimshurst is an electrostatic generator, although it''s not equally efficient, it is useful in science experiments that involves high voltage.
