Hey Volks,

    Gotta chime in here... hopefully one of the engineering types on the List
can clear this up.... Isn't a coil just a transformer with  X number of
windings on the input and  many, many X windings on the output?  And wouldn't
collapse and expansion of the electromagnetic field in the primary induce the
voltage in the secondary?  And lastly, in a steady state where DC is flowing
through the primary without being switched off and on, would there be ANY
current in the output?
