| Abstract(in English) | A new simple method to characterize magnetic field distribution around electric appliances was proposed. The method consists of estimation of the magnetic dipole moment vector which is equivalent to an electric appliance. In the proposed method, the dipole moment vector was assumed to be a scalar value by allowing 6dB uncertainty in the estimated magnetic field, which allows us to easily estimate the position and amplitude of the magnetic dipole moment. The validity of the method was verified by experiments using three types of appliances. In addition, frequency characteristics of the magnetic field were taken into account by considering harmonics components in the magnetic field waveform. We used the proposed method for several types of electric appliances, and estimated their equivalent magnetic dipole moments and harmonics components. The results showed that the proposed method had several advantages compared with other methods, the main one being its simplicity. The conditions required for adoption of the method were also clarified. The method is adequate to quantify the magnetic field distribution around electric appliances. |
