3 These systems have its own character depends on principle for detection due to a difference in feature. Hence, it is important to understand the principle for detection of contaminant and the practical use. 44 No. 89 Mar. 2014 (2) 2 b 2 c 90 3 2 2 MD Detection principle of Metal Detector 3 Relationship between magnetic field and eddy current MD 1) 4 MD 2 2 4 Relationship between magnetic field frequency and signal levels MD MD MD MD MD 5 MD
