Air core energy transfer from small to large coil

Ratios of amperage delivery for primary and secondary are shown for three circumstances: a loaded secondary, an unloaded secondary, and removal of secondary. Einstein seems to be saying is that if we have a cause and effect relationship going on using the magnetic field to convey the effect, it does not matter which end of the application we use to cause the effect. so this becomes the first part of the question. Will these same ratios of delivery work in reverse when the direction of line connected input wires are reversed, making the secondary the primary and vice versa??
