Michael Faraday was an English chemist and physicist. He invented electromagnetic induction in 1831. Electromagnetic induction as defined by Stuart Bushong is: An electric current is induced in a circuit if a part of that circuit is in a changing magnetic field. This observation is summarized in what is called Faraday's Law, or first law of electromagnetism. After a series of different experiments, Faraday established that an electric current cannot exist simply because of the presence of a magnetic field. If the magnets were placed next to a coil, the meter would not generate any current. However, if the magnets are moved back and forth near the coil, the ammeter indicates a current. Without electromagnetic induction we would not have MRI and would not be able to produce X-rays. Autotransformers, step-up transformers and step-down transformers use electromagnetic induction to change currents, so they are capable of producing kVp , mA and direct current using rectifiers when dealing with an explanation of how autotransformers, step-up transformers, and step-down transformers work and function. modify currents to produce X-rays. Electromagnetic induction is really a phenomenon nowadays. If it were not for Faraday's discovery, the medical field would surely have missed one of the most important medical concepts to date. Faraday's inventions helped lay the foundations of electric motor technology, and it is thanks to his efforts that electricity is so important in the world of technology. Electromagnetic Induction Michael Farada...... middle of the paper...... at his best! Electromagnetic induction is really a phenomenon nowadays. If it were not for Faraday's discovery, the medical field would surely have missed one of the most important medical concepts to date. Autotransformers, step-up transformers, and step-down transformers are all governed by electromagnetic induction. Without it they couldn't function, and neither could we. Faraday's inventions helped lay the foundations of electric motor technology, and it is thanks to his efforts that electricity is so important in the world of technology today.
