Correct. Actually your are looking at about 10-15A peak per
kVA input power. Make that a 10kVA pig powered coil and
your grounding system see peak pulses of around 100-150A.
Any resistance in the ground path is not only going to kill coil
performance, but, depending on wire length, might even
become another safety risk. Plus, I think, the interference that
you will create that way will drive electronic equipment (and
your neighbors) crazy.

Coiler greets from Germany,
