Abstract. Magnetogama is an open schematic hand-assembled fluxgate magnetometer. Compared to other magnetometer, Magnetogama is superior in terms of its price and its ease of use. Practically Magnetogama can be used either in land or at-tached to unmanned aerial vehicle (UAV). Magnetogama was designed in order to give an open access to a cheap and accurate alternative of magnetometer sensor, therefore it can be used as standard design which is directly applicable to low budget company or education purposes. Schematic, code and several verification tests were presented ensuring its reproducibility. Magnetogama has been tested with two kind of tests, diurnal variation comparison with two nearest observatorium at Lear-month (LRM) and Kakadu (KDU).

Short summary
In geophysics exploration, measuring earth’s magnetic using magnetometer is necessity to resolve subsurface structure of the earth. In this paper, we offer an open schematic fluxgate magnetometer (Magnetogama) which will help people to understand how the magnetometer work, or build their own magnetometer. It focus on how to assembly and record earth’s magnetic response. Several sensitivity tests were performed in order to make sure that Magnetogama has capability to be used in exploration scale.
