    i have discovered that if you take a transformer shaded pole motor coil or another divice with coils in series with the load you get a big spark where as normaly you can barly see the spark. why idoes it do this? (is it acting like an autotransformer or is it justbecause the field being built up or callapsing)

    Yes, and yes.

    Freq (especially higher ones) have an effect on the spark as well.
