In this paper detection by recognized intelligent algorithm for different magnetic films with the aid of a cost-effective and simple high efficient circuit are realized. Well-known, magnetic films generate oscillating frequencies when they stay a part of an LC- oscillatory circuit. These frequencies can be further analyzed to gather information about their magnetic properties. For the first time in this work we apply the signal analysis in frequency domain to create the Fourier frequency spectra which was used to detect the sample properties and their recognition. In this paper we have summarized both the simulation and experimental results.
► Experimental device of magnetic sensor is demonstrated. ► The device can sense magnetic-material film minimum thickness of 10 μm. ► Novel MATLAB based algorithm is presented. ► Easy to fabricate, cost effective circuitry and device is proposed.
