| Resumo: | In this work has been developed a magnetometer, which every step of
conversion of signs and data acquisition has been realized by software, constituted
solely of a sensor flux saturated, commercial. The magnetometer has got high
sensitivity for measure magnetics fields of low intensity, static or with a little
variations. This kind of sensor behave with base in the saturation of a ferromagnetic
material has been used how core. For improve the instrument, have been elaborated
two programs. The first in Labview language, it does the communication between
sensor and user through computer, the app produced is responsible for get and save
the data relative to the sensor's output signal. The second program made in Java
language is delegated for the conversion of data to study them, also save in various
formats and plot graphics. The results are of great importance to study of behavior of
the geomagnetic field, because the variations of magnetic flux will induce electrical
currents in surface of earth, so affect the distribution of electric energy and the
telecommunication Systems. Showed to be possible, with this magnetometer, to
study the variations of fields in magnetic storms and in period considered calm. |
