MAGNETIC BODY DETECTION DEVICE, PROGRAM FOR CAUSING COMPUTER TO PERFORM MAGNETIC BODY DETECTION FUNCTION, AND COMPUTER-READABLE RECORDING MEDIUM FOR RECORDING PROGRAM

摘要

Provided are a magnetic material detection device, a computer program for driving a computer to implement a magnetic material detection function, and a computer readable recording medium recording the program, which can improve detection accuracy of a magnetic material when the magnetic material is detected by using output values of two magnetic sensors.;The magnetic material is detected by using time change amounts of the output values of the two magnetic sensors (measurement sensor portion, reference sensor portion) arranged at a mutual interval of a predetermined distance with a subject positioned outside a space therebetween, so that the magnetic material can be detected while an influence of a change in the geomagnetism on the magnetic sensors is eliminated as much as possible. Therefore, when the magnetic material is detected by using the output values of the two magnetic sensors, the detection accuracy of the magnetic material can be improved.
