Based on your description, it sounds like this is referring to a tuning
coil, in series with the primary, for fine-tuning the primary inductance.
Since the main primary has only two turns, this allows an easy way to very
the primary frequency in small increments. If Tesla was studying secondary
capacitance, seeing what added, known primary inductance can offset a
secondary capacitance is a good way to do it.
As far as "adjusting the primary e.m.f.", emf (I think) refers to the
voltage. I don't think the voltage is what was being adjusted.

In studying Tesla's measurements of capacitance variation one cannot miss the
attention Tesla gives to a regulating coil. In his regulating coil, Tesla
using two fixed turns of primary around the secondary and then has a separate
regulating coil for adjusting the primary e.m.f.. The regulating coil is
considered to be part of the primary. Has anybody on this list used a
regulating coil and have posted results for its use?
