A simple analytical model for magnetic field of a circular current was evaluated for the case of 4-multilayer solenoid of single-pole magnetizing fixture. The exact solution of the analytical model was computationally simulated and presented as 2D spatial distribution of magnetic field strength as functions of applied current and the position of each single coil in the solenoid. The results were compared with experimental measurements performed on commercial magnetizing fixture in order to gauge the effectiveness of the model in real application conditions. Qualitatively, the model shows an excellent agreement to the general trend of spatial distribution of magnetic field patterns obtained from experimental data despite of a considerable percentage error between the model and experimental results.
