A three component ring core fluxgatc magnetometer was constructed to record geomagnetic daily variations in the Brazilian Equatorial Electrojet Region during the IEEY (International Equatorial Electrojet Year) period. The ring core sensor and electronic circuits of the magnetometer arc accommodated in a PVC tube with a diameter of 20 cm and height of 35 cm. The magnetometer has three analog outputs of + 5 volt or + 1000 nanoTesla corresponding to the H, D and Z components. It has a precision better than 1.0 nanoTesla. The magnetometer showed an acceptable performance in monitoring the daily variations in the H, D and Z components of the geomagnetic field.
