With the secondary shorted, the core has essentially no effect,

I think the leakage inductance still depends on permeability.

It probably will, but not much, since the shorted secondary is doing its
damnedest to keep flux out of the core.




In order for ANY energy to pass from the primary to the secondary,
it MUST pass through the core. Perhaps you were making some vague
reference to stored energy?

nope. If they are wound concentric (and possibly interleaved) then there
is still plenty of coupling, sans core.


That depends on the frequency. The lower it gets, the less coupling
will occur without a core.

Of course the magnetising inductance is low, so Imag is high, and they puke flux everywhere, but the core losses are extremely low, and the overall result can be cost-effective. ...
