Answer:

Essay Electromagnetic Induction

  • Michael Faraday was a chemist and physicist from England. He invented electromagnetic induction in 1831. Electromagnetic induction as defined by Stuart Bushong is: An electric current is induced in a circuit if some part of that circuit is in a changing magnetic field. This observation is summarized in what is called Faraday’s Law, or the first law of electromagnetics. After a series of different experiments, Faraday determined that an electrical current cannot exist just by the presence of a magnetic field. If magnets are set next to a coil, the meter would generate no current. Yet if the magnets are moved back and forth near the coil, the ammeter indicates a current. Without electromagnetic induction we would not have MRI.
  • He invented Electromagnetic Induction in 1831. Faraday experimented with magnet fields carrying DC electrical currents. Faraday found that magnetism affected light rays and that there was a relationship between the two. His inventions helped to form the foundation of electric motor technology, and it is because of his efforts that electricity is so important in the technology world. Michael Faraday invented an early form of the Bunsen burner and the system of oxidation numbers, “he was partly responsible for coining many familiar words including electrode, cathode and ion” (BBC, 2011). Faraday had little formal education and only knew a little bit of higher mathematics. Nonetheless, even though he only had education until the age of 14, he became one of the most influential scientists in history.
