Abstract

See full text

A system for searching and sensing reinforcing steel in reinforced concrete is provided. The system comprises a means for magnetizing the reinforcing steel in the reinforced concrete with lines of magnetic force generated by a magnetic field and a means for sensing the lines of magnetic force radiated from the magnetized reinforcing steel to detect an existence and a condition of the reinforcing steel in the reinforced concrete. The sensing means includes a coil for sensing a magnetic force and the magnetizing means is positioned remote from the sensing means.
