you just about answered your own question.
Another transformer question:
What prevents current overload on a primary side of a transformer
when there is no current flow in the secondary windings? As I understand
it, the current flow in the secondary opposes a flow of current in the
primary. If there is no load in the secondary, isn't there basically an
open circuit in the primary, or does the reactance of the primary prevent
current flow until a secondary field exists in the secondary windings?

(Yes).
you don't have a complete open circuit
but what ever the inductance is in the primary
windings.
placing a load on the secondary side will cause
load effects on the primary side..
one neat thing i did years ago was to use a
primary side of a xformer as part of a low freq
oscillator and cause load effects on the secondary
side to change the inductive value of the primary
thus change the frequency of the oscillator.
