Hall effect sensors can be used to monitor the spatiotemporal field dynamics. However, measurement of the z component of the magnetic field (Bz) requires very large dynamic range for the Hall effect sensors due to superposition of encoding fields with main magnetic field (B0). Instead, we propose to measure the transverse components of the magnetic field in several spatial positions to reconstruct spatiotemporal dependency of Bz and we have demonstrated reconstruction of the first order spherical harmonic field distributions.
