Eddy currents

  1. Feb 20, 2007 #1
    someone knows how eddy currents in transformers are produced? by friction , resistance or heat transfer?
    i mean the classical example is the wheel that is braked between the poles of an electromagnet, but how this applies to a transformer where there is exactly the opossed, a fixed conductor and variable magnetic field

    (btw, english is not my native , so i always thought eddy currents was named because a scientist named eddy, just todays little discovery )

    Yes,*someone* quite possibly knows.Eddy currents ,namely in ferromagnetic core,aren't produced by "friction ,resistance or by heat transferr".
    They are produced by alternating magnetic field by Faradey's law of Electromagnetic induction.

    To moderator:This question is the most suitable for EE subforum.Move it there
