MATLAB computations and experimental measurements of the magnetic fields between two filamentary circular (FC) coils are presented in this paper. In order to achieve accurate computations, the induced voltage and current in the secondary side of the coil are determined and validated with measured values. The findings are obtained by formulating the models for computing the total magnetic flux through the secondary coil and mutual inductance between the two FC coils. Based on a more efficient and general model available in the literature, the model for computing the magnetic fields between the coils is derived. The comparison of the superimposed computed magnetic fields results and measured values show that the model formulated and experimental measurements implemented in the laboratory are accurate.
