Abstract :
This paper presents a method for estimating the 2D position of a magnetic dipole from measurements of the first order Fourier coefficients of its magnetic flux density on a circle with an arbitrary radius. It is proved that the azimuth of the dipole is equal to the phase of the first order complex Fourier coefficient. The method is verified by experiments using coils which can directly measure the Fourier coefficients.
