As the drawings show in EN61000-4-8, one way to achieve the required field
is to let the ground plane be the fourth side of a square loop. I have
found it more convenient to construct stand-alone loops that can be placed
over and under the EUT which is supported above an appropriate ground plane.
There is indeed a relationship between Teslas and Gauss, but admittedly it
took some 'dusting' of the old physics texts when EN61000-4-8 (Power
Frequency Magnetic Field Immunity) testing became a requirement under the
new light industrial/residential immunity standard.
