| Abstract | The geomagnetic field undergoes regular transient changes and also long period secular variations. The study of geomagnetic variations provides understanding of electric currents in the ionosphere and magnetosphere of the Earth. Monitoring of geomagnetic variations is a part of the space weather studies. The objective of this work is to report the results and the construction a cheap ring core three component fluxgate magnetometer to record geomagnetic variations in the central region of the South Atlantic Magnetic Anomaly (SAMA) at the Southern Space Observatory - SSO/CRS/CIE/INPE - MCT, (29S, 53W), São Martinho da Serra, RS, south of Brazil. The magnetometer described here is constituted by three orthogonal sensors (H, D, and Z components) with a toroidal nucleus. The functioning of this sensor is based on properties of high permeability material of the ring core. Each sensor is composed for two bobbins in each axis, one for excitement and another bobbin for the second harmonic signal detection which is proportional to the surrounding magnetic field. After the comparison of the signals is made follows the stage of an integrator which provides smoothed variations proportional to the surrounding geomagnetic field. This type of a magnetometer is a versatile equipment for the detection of geomagnetic field ranging from 0,1nT to 1mT. The experimental studies for the construction of a cheap equipment but with good sensitivity level may open the possibility to increase the number of sensors installed in the region of the South Atlantic Magnetic Anomaly - SAMA - in south of Brazil and other countries of South America. |
