"  Coilers are apparently not familiar with the induction field around
the
Tesla coil. If I understand this field correctly a coiler should be able
to
detect the field with a compass placed near a TC while it is energized.
The
compass is not sensitive to the EM field but should deflect because of
the
magnetic effect of the induction field. The compass would have to be
properly aligned and very close to the center of the secondary winding.
Has
anyone tried this test? Reinhart's lamp could be used but this is also
sensitive to the EM field.

        For this test you'd want to run a small DC current through the coil.
Field falls off inversely as the cube of the distance.
