... All modern smartphones possess a magnetometer as part of their internal compass [12,13], and these magnetometers can be utilized to capture the steels magnetic profile [14]. In addition, we showed that the dynamic magnetic signatures corresponded to the chemical composition of the steel blade and its Vickers microhardness [15,16] We recently extended the ability to use electromagnetic signatures to analyze chemical composition to bronze artifacts [17]. Since copper and tin have different electrical conductivities (with tin only having 15% of copper's electrical conductivity), bronzeware of different copper-tin ratios will have different electrical conductivities and, thus, different dynamic electromagnetic profiles [18]. ...
