  Let us see - - the definition you quoted maid no mention, even
indirectly concerning *moving* parts.
  And the last time i looked, each (individual) piece of copper , iron,
plastic, glass, whatever does not move...
  And the combination of the copper and iron uses the magnetic
properties of (solid) iron; which fits the quote exactly...
  BTW, iron has a rather definitive crystalline structure, and since
annealed OHFC is not used for the coil, then the copper also has a
crystalline structure.

  Mind you, i am not arguing.
  Just point out a few iregularities...
