センサー。A magnet is movably arranged in a case containing at least the tip of a fiber bundle consisting of a light transmitting fiber whose rear end is connected to a light source and a light receiving fiber whose rear end faces a light receiving element. A magnetic body is movably attached to the outer periphery, and the position of the magnetic body is adjusted so that the magnet is brought into contact with the end face of the fiber bundle with a weak force. When the magnet is drawn, a gap is formed between the magnet and the end face of the fiber bundle, and the light from the transmitting fiber is reflected by the magnet depending on the gap, and the reflected light is received by the receiving fiber and detected. A sensor that detects minute magnetic substances.
