Desenvolvimento de um magnetômetro fluxgate para estudos de clima espacial e aeroespacial. 2015. 81f. Dissertação (Mestrado em Ciências Climáticas) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2015.https://repositorio.ufrn.br/jspui/handle/123456789/20344In 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.porAcesso AbertoFluxo saturadoLinguagem LabviewGeomagnetismoTempestades magnéticasmasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA: CIÊNCIAS CLIMÁTICAS
