Type of experiment Three pairs of 6 cm diameter spherical probes (P1-P6) were mounted
at the end of 15 or 7.5 meter wire booms and a tri-axial search coil magnetometer,
with one coil parallel to spin axis and the remaining in the spin plane
(i.e, one radial and another tangential in the spin plane)
