This work shows a study of hysteresis loops in steel to identify different ferromagnetic magnetization mechanisms. Some hysteresis loops have been studied in different zones of the principal loop. A magnetometer was used to measure the magnetization changes and a DC power supply to give current to a coil to create a magnetic field. Having the results, we defined a degree of irreversibility for each loop and plotted it against the different parameters of our experiment5 p.application/pdfengcc-by-nc-nd (c) Rebolledo, 2020http://creativecommons.org/licenses/by-nc-nd/3.0/es/AcerHistèresiTreballs de fi de grauSteelHysteresisBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
