Agreed about the heating caused by current, but the current flowing
in the wires of an air-cored transformer can easily be in the tens of
Amperes range. Depends how much energy you feed in doesn't it? There
must be few Tesla Coils out there with a milliamp or less flowing in
their windings at some point or another.
