                         important information about the Magnetosphere, the Earth/Sun 
                         interaction, as well as Ionosphere's events occurrences which can, 
                         for instance, generate disturbances in telecommunications or even 
                         in the space whether. Specially in the area where is observed the 
                         lowest intensity of the Earth's magnetic field in the Global 
                         surface, the South Atlantic Magnetic Anomaly SAMA, where 
                         frequently occurs larger scales events, mostly because the great 
                         particles precipitation in the form of magnetic storms, due to the 
                         low magnetic field intensity. To improve the knowledge and the 
                         understanding of the Earth's Magnetic Field behavior in the SAMAs 
                         area it has been developed a fluxgate magnetometer with ring-core 
                         in the Southern Regional Space Research Center CRS/INPEMCT in the 
                         south of Brazil. The magnetometer has its operation based on the 
                         iron magnetic properties of the high permeability ring-core. 
                         Varying the magnetic permeability of the nucleus through a high 
                         frequency excitation signal it is possible to obtain a response 
                         that changes the magnetic saturation around the nucleus as in the 
                         (BxH) Histereses curve. The sensor coil detects a signal with high 
                         harmonic content which is related with the Earth's Magnetic Field 
                         in the observation region. This paper has the intention to show 
                         the way used to implement the sensor, the electric circuit and
