The switch on the sensor shaft is used to select the range. On the 6.4 mT range,
each volt measured by the transducer represents 32 gauss (3.2 × 10
-3
tesla). The
range of the sensor is ±64 gauss or ±6.4 × 10
-3
tesla. On the 0.3 mT range, each
volt measured represents 1.6 gauss (1.6 × 10
-4
tesla). The range of the sensor is
±3.2 gauss or ±3.2 × 10
-4
tesla.
If the sensor tube is held vertically with the tip horizontal, and rotated until the
maximum voltage is found, the tip with the white dot will point to magnetic
north. The magnetic inclination in your area can be found by holding the tube so
that the white dot is facing north, and rotating the sensor end of the tube down
until the voltage reaches a maximum. The angle of the tip from the vertical
position is the magnetic inclination. Note that the north pole of a freely suspended
magnet points north, since the magnetic pole of the Earth in the northern
hemisphere is a south magnetic pole.
Troubleshooting
If you are getting unexpected or unusual readings from the Magnetic Field Sensor,
first confirm that the range setting is appropriate for the experiment. The ±6.4 mT
range is used to measure relatively strong magnetic fields around permanent
magnets and electromagnets; the ±0.32 mT range is used to measure the magnetic
field of the Earth and very weak fields. If you are using the ±0.32 mT range for
investigating permanent magnets, make sure that the sensor remains in one
position so that the reading is not affected by the background field of the Earth.
