A very useful facility to have.

Perhaps a couple of turns of wire about the same diameter as the Primary on
a piece of insulating sheet placed above the primary. This winding could be
terminated in a resistor to absorb the coupled energy.
A high coupling coefficient would rapidly remove energy form the primary.
BTW I've not actually tried this idea

I realise this load does not have the interactive dynamics of a true
secondary but it might be useful for some types of testing such as gap
firing voltages.
