Fluxgate magnetometers play a crucial role in geophysics and space physics. Fluxgate magnetometers are used to measure weak magnetic field, thanks to their high sensitivity, robustness, compactness. In this study, the architecture of the system, materials science, principles and linearity of the constructed sensor will be focused. For use in Vacquier type fluxgate magnetometer, pre-annealed high precision VITROVAC 6025Z ribbons were subjected to magnetically heat treatment for 1.5 hours under 1000 A/m magnetic field under below Curie temperature. VITROVAC 6025Z ribbons, which are not heat treated and heat treated under magnetic field, were evaluated with the help of DC Permeameter. Annealed VITROVAC 6025Z ribbons were placed on Vacquier type bobbins made in a 3D MSLA printer, and a printed circuit was created for analog excitation of the physical sensor and the sensor connected to it. A calibrated auxiliary fluxgate magnetometer was used to examine the sensing coil signal of the sensor. The sensor created in the light of these methods has been found to have low coercivity, low field-induced anisotropy, and high magnetic permeability. In addition, the sensor detected magnetic fields of 19µT and above without compensation or closed-loop gain circuit. It has been observed that the output voltage saturates in magnetic fields above 49µT. By comparing the data we obtained from our experimental studies with the literature, it was determined that there was a need for improvement studies. It is evaluated that our study will help fill the current research gap in fluxgate type sensors.
