I realize AC is not DC.  This is a potential transformer.  That is, it
produces high voltage DC potential.  There are no center taps.  It is AC in,
DC out, two wires in, two wires out.  The transformer is made by
Westinghouse and is model 1023084C.

The coil is merely charged with 50KV in my arrangement.  There is no current
flowing as there is no closed loop.

I still don't know why the coil induces a voltage.

I hope you dont have a center grounded transformer.The current flow of your
coil is from your transformer to the coil through the air-coil capacitance
through ground and back to the transformer. Your coax acts like a
transformer winding fed through capacitance of the insulation. Ac is NOT dc
