Abstract
The present invention uses a plurality of magnetic field sources and magnetic field sensors mounted against a surface. Based on the mass of ferromagnetic material, such as steel, the magnetic field sensors detect variable magnetic field strength and this variance is proportional to the mass of ferromagnetic material being detected. An electronic device reads the magnetic field values and uses the information to quantify the ferromagnetic material in the surface or inside the volume of the construction component.
