A magnetic contamination detection system based on high sensitive induction gradiometer is presented. This system is free from heavy cooling system, and the magnetic sensor consists of coil and simple electronics only. This paper considers the detection limit of two kinds of wire, SUS304 and Fe. It is found that the detection limit and profile of output signal are differs from the wire material. When the length of wire is 10mm, our system can detect a SUS304 wire having 0.2mm diameter, and an Fe wire having 0.1mm diameter.
