ABSTRACT: This work presents the geomagnetic characterization of the municipality of Macaé, Brazil. Data from IGRF12 (twelfth edition of International Geomag-netic Reference Field) were used. Through the data collected in a regular grid of 0.1 degrees of the components, north, east and vertical were generated maps of components, inclination, declination, horizontal component and geomagnetic total field. The results showed important relative variations of these magnitudes, such as the magnetic declination that varied around 0.2 degrees along the area of the municipality, which is a considerable value and capable of causing significant changes in directions by compass in the studied region.
