Geomagnetic field over Akure was monitored and measured using a locally produced magnetometer. The geomagnetic data generated were evaluated at every local time hour. Diurnal, monthly and Seasonal effects were investigated. The results of the analyses from the magnetic data generated provide a comprehensive understanding of the geomagnetic variation over the region. This research validates the instrument and presents a direct measurement opportunity to capture the influence of local sources.展开更多
