emags 3 inductance

• Inductance


  The property of an electrical conductor by which a change in current through it induces an electromotive force (voltage) in both the conductor itself (self-inductance : L) and in any nearby conductors (mutual inductance : M)

  
• The unit of inductance is the Henry, named after Joseph Henry (1797 1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791 1867) did in England
• The symbol L for inductance was chosen to honor Heinrich Lenz (1804 1865), whose pioneering work in electromagnetic induction was instrumental in the development of the final theory
• Faraday's law of electromagnetic induction


  States that any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil

  
• Self-inductance (L)


  The property of an electrical conductor by which a change in current through it induces an electromotive force (voltage) in the conductor itself

  
• Mutual inductance (M)


  When an EMF (voltage) is produced in a coil because of the change in current in an adjacent or coupled coil

  
• Transformer


  An electrical device that transfers electrical energy (voltage and current) between two or more circuits through the principle of electromagnetic induction
• Where: V = Voltage, I = Current, N = Number of loops or turns, Subscripts: P = Primary Side, S = Secondary Side
