Faraday anticipated the theory of electromagnetism. He researched on the magnetic field around a conductor carrying a DC electric current, and estimated the source for the magnetic field concept in physics. According to his theory, magnetism can affect rays of light and there is an underlying relationship between these two phenomena.
Michael Faraday built two devices to produce what he called electromagnetic rotation: that is a continuous circular motion from the circular magnetic force around a wire. Ten years later, in 1831, he began his great series of experiments in which he discovered electromagnetic induction. These experiments form the basis of modern electromagnetic technology.
In 1831 using his induction ring, Michael Faraday made one of his greatest discoveries, electromagnetic induction - the generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In his second series of experiments in September he discovered magneto-electric induction - the production of a steady electric current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.
Though Faraday was a less educated person and was not much aware of high-grade mathematics such as calculus; still he is known as one of the most influential and talented scientists ever. Michael Faraday continued his electrical experiments. In 1832, he proved that the electricity induced from a magnet, voltaic electricity produced by a battery, and static electricity were all the same.
He also did significant work in electrochemistry, stating the First and Second Laws of Electrolysis. This laid the basis for electrochemistry, another great modern industry. Apart from Electromagnetic induction, he also discovered diamagnetism and laws of electrolysis.
