Using same coordinate system as the coil, Bartington 3 axis Fluxgate Magnetometer gave the following readings

X = -0.733 V
Y = -0.101 V
Z =  2.391 V

so the total magnitude is sqrt(X^2 + Y^2 + Z^2)

= 2.515 V.

Scale of Fluxgate is 1 Gauss = 10 V, so

2.515 V = 0.2515e-4 T.

The X & Y component should only contribute to the field measured by the coil, so

sqrt(X^2 + Y^2)  =  0.740 V = 7.40e-6 T

The length of the DC 2 coil is 0.457 m.  So 7.40e-6 T  * 0.457 m = 3.382e-6 Tm.

The angle of X and Y is -172.6 degrees

The 0 current measurement of the dipole moment from DC 2 is 2.8389e-06 Tm at   -164.79 deg

These agree fairly well given the alignment difficulties between the coil and the fluxgate
