Electromagnetic Induction is the process of using magnetic fields to produce voltage, and in a complete circuit, a current.. Michael Faraday first discovered it in 1831, using some of the works of Hans Christian . g. eraint.lewis@sydney.edu.au. PHYS 1902. Chapter 29 . Electromagnetic Induction. . Electromagnetic . induction. Main idea:. a . time-varying. magnetic field can act as a source of the electric field. Electric Current. Electric current . – The net movement of electric charges in a single direction through a wire or conductor.. Voltage difference . – The force that causes electric charges to flow; charges flow from high voltage to low voltage.. When the current through an inductor changes, the magnetic field also changes. This changing magnetic field causes there to be an induced voltage across the terminals of the inductor. This induced voltage’s polarity is in a direction opposite to that of the original voltage applied.. , BIOELECTRICITY, AND DC INSTRUMENTS. PowerPoint Image Slideshow. Figure . 21.1.
