New research that influences the direction of applied physics: description of the development of a prototype based on a new methodology. Breakthrough concept using underlying classical physical principles: complex magnetic susceptibility and inductive instrumentation. Great application in many disciplines including fundamental physics, mining, geophysics, geology, engineering, oil industry, etc.A device named magnetic susceptometer for a complete determination of the magnetic complex susceptibility of materials and minerals has been conceived and manufactured as a complement for the in situ characterization of rocks during high resolution magnetic prospections. In this work a device and its capabilities for susceptibility measurements are described, the calibration performed with artificial samples, and the values of real and imaginary susceptibility of natural samples in a range comprising: χ = 10−4 to 10−7 [SI], representative of Earth and also Mars rocks.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttps://creativecommons.org/licenses/by-nc-nd/4.0/Magnetometric devicePortable suscetometerInductive deviceMagnetic susceptibilityInductive methodsInductive devicesMagnetic surveysMagnetic characterizationSusceptometerinfo:eu-repo/semantics/article10.1016/j.sna.2017.07.015info:eu-repo/semantics/openAccess
