The winding that lies in the slots

The winding that lies in the slots of the E consists of 66 turns of 18 AWG wire heavy build insulation, for approximately a 66% copper fill fraction in the coil window. It is assumed that the core extends for 1 inch in the intothepage direction. For the purposes of this model, the material is assumed to be a linear ferromagnetic material with a relative permeability of 2500.
