Adam,

Although the coupling is tight between the primary and secondary,
this means nothing, because the "overall" coupling or effective coupling
of a magnifier is still loose.

The coupling is not really higher.  If there's any benefit from a magnifier,
it would be gained by  following Antonio's formulas which permit all the 
energy to be captured in the extra coil at one time.

In typical magnifiers that have been built, there is no advantage
efficiency-wise.  There are some possible layout advantages, for 
instance the magnifier may fit into a smaller building, etc.
