Abstract
The pulsation magnetometer at Ethio-Finno Observatory (EFO) has been operational
since June 2004. The major objectives of this instrument is to characteristically investigate
the ionospheric phenomena of the upper polar atmosphere. Results from the
data analysis in time and frequency domain depicts existence of strong interferences
which are not observed in other similar observatories. In this thesis we shall investigate
the disturbance characteristics and delve out the cause of peaks by relating with
solar activities, geomagnetic activities and local effects such as ferrous object, and
ground loop. This is done by carefully investigating the data collected during some
days and by conducting controlled experiment
