Hi all,
Please find attached the Excel file with the holding field
measurements.
V6,V7 and V8 are actual voltages measured from 3 Hall probe
components, H6,H7 and H8
are corresponding magnetic fields. In first approximation, H6
corresponds to long. field, H8 - to
transverse field and H7 - vertical component.
From that Htot, theta and phi are calculated.
Now, I do know that the probe had a roll of about 1.6 degrees and
pitch of about .9 degrees.
I do not know the most important angle - pitch, it was impossible to
measure with given apparatus
with necessary accuracy. New gear will be machined and new measurements
will be done after the run.
