Annex A of IEC 61786 specifies the field at the center of a square loop with side dimensions of 2a to be
B = 1.414 u I N / pi / a, where B = the normal field component at the center u = permeability of air I = Current in Amps N = turns If the loop is 1 m square, the field will vary no more than 1% over a 10 cm probe. I have used this loop to calibrate a probe at 58 kHz.
