Research and Design for Three-Axis Electromagnetic Leakage Detector

In order to measure the magnetic field around electronic products, household appliances and industrial electrical equipment, this paper puts forward a new method which makes use of electromagnetic coupling design based on three-axis electromagnetic leakage. This method can overcome the disadvantage of traditional single-axis measurement which needs to get the total magnetic field after several times’ measurement. This paper designs three-axis electromagnetic leakage detector for circuit measurement, which is proved to be correct after circuit measurement experiment. It can easily detect 30-2K Hz leakage magnetic field of low frequency generated from electrical appliances products.Introduction.
