- Michael Faraday (1791-1867) is probably best known for his discovery of electromagnetic induction, his contributions to electrical engineering and electrochemistry or due to the fact that he was responsible for introducing the concept of field in physics to describe electromagnetic interaction.
- Hi I'm Michael Faraday
- In 1845, just 170 years ago, I discovered that a magnetic field influenced polarized light – a phenomenon known as the magneto-optical effect or Faraday effect.
- .To be precise, he found that the plane of vibration of a beam oflinearly polarized light incident on a piece of glass rotated when a magnetic field was applied in the direction of propagation of the beam. This was one of the first indications that electromagnetism and light were related
- He explained electrolysis in terms of electrical forces and also introduced concepts such as field and lines of force, which not only were fundamental to understanding electrical and magnetic interactions but also formed the basis of further advances in physics.
- The following year, in May 1846,
- I published the article Thoughts on Ray Vibrations, a prophetic publication in which I speculated that light could be a vibration of the electric and magnetic lines of force. I discovered electromagnetic induction, which led to the invention of the dynamo, the forerunner to the electric generator.
- As he explained years later, the wire was surrounded by an infinite series of circular concentric lines of force, which he termed the magnetic field of the current. He also wanted to determine whether magnetic fields had an effect on optical phenomena. Faraday formulated that electromotive force produced around a closed path is proportional to the rate of change of the magnetic flux through any surface bounded by that path.
- I also wanted to determine whether magnetic fields had an effect on optical phenomena.
- His inventions transformed the home, farm, and factory. From cell phones to air conditioning, the modern conveniences we now take for granted were once but a fantasy without Faraday’s relentless wonder and curiosity to fuel them.
- He devoted his life to teaching others. Throughout his lifetime, even while struggling with dementia and depression for decades, Faraday’s devotion continually pushed the boundaries of science — and the world has never been the same since.
