Third law reaction question

I have attached a drawing that depicts the situation of two electromagetic coils in space separated by a vast distance. It seems to me that in this case there would be a magnetic action force on the right coil but no reaction on the left coil. I'm probably missing something here but I would appreciate any pointers on what that might be. If the description or graphic is unclear, please let me know.

Thanks!

Newton's third law (in fact, the force concept as such) only holds if the propagation speed of the interaction is infinite. I have examined a similar problem (a retarded interaction when the objects are moving relatively to each other) on my webpage http://www.physicsmyths.org.uk/retard.htm.

Thomas, may be you need to use Lorents transformations (instead of Galilean) between systems?
