Abstract. Magnetogama is an open schematic hand-assembled fluxgate magnetometer. Compared to another magnetometer, Magnetogama has more benefit concerning its price and its ease of use. Practically Magnetogama can be utilized either in land or attached to an unmanned aerial vehicle (UAV). Magnetogama was designed to give open access to a cheap and accurate alternative to magnetometer sensor. Therefore it can be used as a standard design which is directly applicable to the low-budget company or education purposes. Schematic, code and several verification tests were presented in this article ensuring its reproducibility. Magnetogama has been tested with two kind of tests: a comparison with two nearest observatories at Learmonth (LRM) and Kakadu (KDU) and the response of magnetic substance.

Short summary
In geophysics exploration, measuring earth's magnetic field using magnetometers is a necessity to resolve earth's subsurface structure. In this paper we offer an open-schematic fluxgate magnetometer (Magnetogama) that will help people build their own magnetometer. We focus on how to assemble and record earth's magnetic response. Several sensitivity tests were performed to make sure that Magnetogama has the capability to be used in exploration.
