Abstract :
This paper presents the design criteria of a magnetometer suitable for the measurement of magnetic field in the frequency range 0.01 Hz-10 kHz with reference to human exposure. The proposed apparatus is designed in order to be integrated in remote sensing sensorial network for monitoring the spatial distribution of the 3D components of the magnetic field density vector. The theoretical design criteria are confirmed by the reported preliminary experimental results
