Magnetic evaluation of rebars

Keywords: nondestructive testing NDT; nondestructive evaluation NDE; magneto-optical (MO) sensor; anisotropic magneto resistance (AMR) sensor; reinforcement bars detection; rebars; concrete inspection; reinforced concrete

The data was collected as a part of the project National Science Centre (in Polish: NCN—Narodowe Centrum Nauki), program: Preludium, grant number 2021/41/N/ST7/02728 (“Smart support system for the Magnetic Force Induced Vibration Evaluation (M5)—an electromagnetic, nondestructive method designed for the evaluation of composite materials containing ferromagnetic and conductive elements.”).

The data was used in the papers:
