Once you get to the right side do you (A)..keep winding the second layer from the side you ended the first layer, the right side in this example, and move left or do you (B)..end the first layer on the right and then immediately return to the left side and start the second layer and continue moving right again? Sorry if this sounds confusing but I wonder if this affects the inductance at all? Thanks

Hi;
No you work your way back and forth across the bobbin, left to right, then right to left, other then the leads which are buried under the wrapping. Field coils, unlike RF and oscillator coils, are not that fussy about how they are wound, as long as the wire gauge is think enough and the coil has enough turns to be close enough in terms of inductance, the object here is to produce a magnetic filed, and block the 120 cycle AC ripple.
