Type of experiment 4 spherical probes covered with vitreous carbon were placed at the ends of
4.5-m booms to serve as the sensors. A triaxial fluxgate magnetometer
with a frequency-dependent feedback loop was employed as the sensor
for the frequency range of 0.2 to 6.5 Hz while a search-coil magnetometer
was used for the high frequency range.
