It's true that there is magnetic coupling between the primary and 
secondary of a classic TC.  NT did a lot of work in his later years 
with electrostatics and longitudnal electricity in his coils.  Some 
provocative posts have been written in this regard.

Most TCers are hung up on only magnetic fields transferring energy in  
TCs. To be sure, there is mutual inductance and magnetic coupling 
between primary and secondary.  But, there are also resonant 
electrostatic fields that couple between the primary and secondary.  
These are special fields in that there may be superpositioning of the 
electrostatic fields as opposed to macromagnetic fields that do not 
superpose.  Both the secondary and primary have inherent isotropic 
capacities that exchange energy as they resonate.  Perhaps energy 
passes one way magnetically and the other electrostatically.  Resonant 
voltage rise probably has more to do with intrinsic coil capacities and 
electrostatic electricity in an active rather than passive role.  There 
is mutual coupling between both the magnetic as well as the 
electrostatic components of conventional Tesla Coils.  Each requires 
the other.  It is error to consider only electromagnetic energy 
transfer to the exclusion of electrostatic energy transfer. 

An attempt to measure static capacities in both primary and 
secondary coils should be carried out.  Measurement with the TC coil 
assembled to determine mutual capacitance, coupling and electrostatic 
fields of both primary and secondary statically and dynamically should 
be attempted.  This is a good place for gradiometer (directional 
electrometer) field measurement while driving the coils with a signal 
generator.
