In order to measure the magnetic field around the electronic products, household electrical appliances, industrial electrical equipments and other electrical products when they are running to know the status of electromagnetic radiation of running electrical products, a new method for the detection of Electromagnetic leakage intensity based on three axis designed by using the principle of electromagnetic coupling are presented, which can overcome the problem that the traditional single-axis measurement requires multiple measurements to get the total magnetic field vatue, and three-axis electromagnetic leakage detector is designed for actual measuring circuit, whose validity has been tested and verified by actual measuring circuit experiment. The detecting instrument can easily detect the values of magnetic field intensity of low-frequency leakage of 30 kHz -2 kHz generated by electrical products.
