We have 1 magnetometer. It is a 3-axis fluxgate magnetometer (Bartington Mag-03MC100 Sensor).

[http://nodus.ligo.caltech.edu:8080/40m/1933 Kevin's Magnetic Measurements]:
Since Kevin used the above fluxgate seismometer, we can convert his voltage measurements (below) into magnetic field by using the manual's guess of 10 uT /V or 10 V/Gauss.
