I'm with MAG, and his earlier description. It can't matter which side of the coil a resistor is on.
If you have a problem with which component the electricity gets to first, just switch between thinking of current as defined in physics books (direction of positive charge flow) and current defined as flow of electrons. They go in opposite directions, so you can pretend it's going in whichever end you prefer--but the car doesn't care.
